18 Best Korean Crime Series on Netflix to Watch
If you are searching for the best Korean crime series on Netflix, there are plenty of different styles to explore. My Name delivers undercover action, Bloodhounds takes viewers into the dangerous world of loan sharks, and Signal builds its mystery around an unusual connection between detectives. Meanwhile, The Glory explores revenge, while Narco-Saints focuses on an undercover operation against a drug empire.
This list ranks 18 compelling Korean crime dramas and crime-focused thrillers based on their storytelling, suspense, character development and appeal to fans of the genre. Some lean towards action, while others are more interested in forensic clues, psychological tension or social commentary.
1. My Name
Genre: Action, crime thriller, undercover investigation
If you want a Korean crime series that gets straight into its central mystery, My Name is an excellent place to start. Han So-hee plays Yoon Ji-woo, a young woman whose life changes after her father is murdered. Determined to discover who killed him, she turns to powerful crime boss Choi Mu-jin, who trains her before she infiltrates the police force.
Ji-woo’s undercover assignment puts her between two dangerous worlds. She must build trust with fellow officers while remaining connected to a criminal organisation, and every new discovery makes her mission more complicated. The series combines a personal revenge story with police corruption, organised crime and violent confrontations.
What makes My Name particularly effective is its physical intensity. Han So-hee’s performance gives Ji-woo’s anger and isolation a convincing edge, although viewers looking for a slow, clue-heavy detective mystery may prefer a more procedural series. Its eight-episode structure also makes it a manageable weekend watch.
Why watch it: Choose My Name for a gritty Korean undercover crime drama with revenge, betrayals and hard-hitting action.
2. Bloodhounds
Genre: Crime, action, organised crime
Bloodhounds follows two young boxers who become involved in a violent conflict with predatory moneylenders. Faced with a criminal network that exploits people trapped in debt, the pair use their fighting skills to protect those being targeted. Their personal loyalty becomes the emotional centre of a story driven by physical confrontations and escalating danger.
The series works because its crime premise has a clear human cost. Debt is not simply a plot device; it is the mechanism that allows powerful criminals to exploit vulnerable people. Against that background, the friendship between the two leads gives the action a sense of purpose beyond defeating another opponent.
Unlike detective dramas that rely on hidden clues and lengthy investigations, Bloodhounds is more direct. Its strength lies in the momentum of its fights, the contrast between its protagonists and their enemies, and the question of how far ordinary people can go to protect others.
Why watch it: It is a strong choice for fans of Korean gangster dramas, boxing action and crime stories about friendship and financial exploitation.
3. Signal
Genre: Detective thriller, mystery, crime
For viewers who prefer solving a mystery to watching nonstop action, Signal is one of the most distinctive Korean crime dramas to seek out. The story centres on detectives who communicate across different time periods through a mysterious radio connection. Information from the past can influence investigations in the present, but changing events also brings unexpected consequences.
The unusual premise gives the series a way to revisit cold cases, missing evidence and crimes that were never properly resolved. Its central appeal comes from the relationship between investigation and consequence: a discovery that appears to offer a breakthrough can also change what happens next.
Signal is especially rewarding for viewers who enjoy stories that connect individual cases to broader questions about police accountability and justice. Its emotional stakes are closely tied to the victims and families affected by the crimes, rather than treating each mystery as a puzzle to be solved and forgotten.
Why watch it: Pick Signal for a layered Korean detective series that blends cold cases, suspense and a supernatural twist.
4. Stranger
Genre: Legal crime thriller, police investigation, corruption
Stranger, also known as Secret Forest, follows prosecutor Hwang Si-mok and detective Han Yeo-jin as they investigate crimes connected to corruption and powerful institutions. Si-mok’s unusual emotional detachment influences how he approaches his work, while Yeo-jin brings a different perspective to their partnership.
The series places as much emphasis on systems and motives as it does on individual suspects. Evidence can lead towards people who appear respectable, and institutional influence can make it difficult to determine where responsibility truly lies. Instead of relying on a single obvious villain, the story builds a network of competing interests that keeps the investigation complicated.
This is a good option for viewers who enjoy carefully structured mysteries and procedural details. Its measured pace gives the characters and evidence room to develop, although those looking for constant fights or rapid-fire twists may find it less immediately explosive than an action-driven crime series.
Why watch it: Choose Stranger for a sophisticated Korean police and prosecutor drama focused on corruption, evidence and institutional power.
5. A Killer Paradox
Genre: Psychological crime thriller, dark comedy
A Killer Paradox follows Lee Tang, a college student whose life takes a disturbing turn after he becomes involved in a killing. As further events unfold, he begins to believe that some of the people he encounters may be criminals who have escaped justice. Detective Jang Nan-gam becomes determined to understand what is happening and catch him.
The series explores a difficult question: who gets to decide whether someone deserves punishment? Lee Tang’s actions become increasingly hard to categorise as the story moves between crime, dark comedy and psychological suspense. Its premise encourages viewers to consider the difference between justice and vigilantism without making those boundaries comfortable or simple.
Choi Woo-shik gives the central character an unpredictable quality, while Son Suk-ku’s detective provides a compelling counterweight. The shifting tone will not appeal to everyone, but it helps the show stand apart from conventional police procedurals.
Why watch it: It is a strong recommendation for viewers seeking a Korean psychological crime thriller with moral ambiguity, unusual twists and a cat-and-mouse investigation.
6. Narco-Saints
Genre: Organised crime, undercover thriller
Narco-Saints follows an ordinary entrepreneur who becomes involved in a secret government operation targeting a Korean drug lord operating in South America. His business plans lead him into a dangerous criminal environment, where survival depends on deception, careful alliances and knowing when to trust the wrong person.
The series takes the familiar undercover-crime formula and places it within an international drug network. Rather than presenting its central character as a trained law-enforcement professional, it makes his outsider status part of the danger. He has to navigate people whose experience with violence and manipulation far exceeds his own.
With six episodes, Narco-Saints is a relatively compact crime thriller. Its appeal comes from the shifting alliances and the tension of maintaining a cover while trying to help dismantle a criminal operation. The story is inspired by real events, although its dramatic presentation should not be treated as a documentary account.
Why watch it: Choose Narco-Saints for Korean organised crime drama, undercover operations and a story about the risks of confronting a drug empire.
7. D.P.
Genre: Military crime drama, social investigation
D.P. follows soldiers assigned to track down military deserters. Jung Hae-in plays Ahn Jun-ho, who works with his partner to locate people who have left their posts. What initially looks like a straightforward duty becomes more complicated as each case reveals the reasons behind a soldier’s disappearance.
The drama is particularly effective because it asks what happens before someone decides to run away. Bullying, abuse, isolation and rigid hierarchies emerge as important parts of the stories, shifting the focus from simply catching deserters to understanding the circumstances that drove them away.
Rather than relying on a conventional criminal mastermind, D.P. examines institutional failures and the consequences of people ignoring warning signs. Its emotional weight can make it a difficult watch, but the series offers a more grounded perspective than many action-heavy crime dramas.
Why watch it: It is a compelling option for fans of serious Korean crime dramas that investigate abuse, accountability and the systems surrounding criminal behaviour.
8. Juvenile Justice
Genre: Legal crime drama, courtroom investigation
In Juvenile Justice, a stern judge handles cases involving young offenders and must confront difficult questions about responsibility, punishment and rehabilitation. The drama explores how crimes committed by minors affect victims, families and the wider community, while examining the circumstances that can contribute to youth offending.
Its case-focused structure offers a different experience from serial-killer mysteries or gangster thrillers. Instead of following a single criminal investigation from beginning to end, the series uses individual cases to explore the legal system and the people who work within it.
The strongest aspect of Juvenile Justice is its refusal to make every case morally straightforward. Questions about accountability are complicated by age, background and the impact of adult decisions. The subject matter can be distressing, particularly in cases involving serious violence against children, so it is best suited to viewers comfortable with difficult social themes.
Why watch it: Choose this series if you enjoy Korean legal dramas, courtroom conflicts and crime stories that examine justice beyond arrest and punishment.
9. Extracurricular
Genre: Teen crime thriller, psychological drama
Extracurricular centres on Oh Ji-soo, a high-achieving student who secretly runs a criminal operation to earn money. His carefully managed double life begins to unravel when classmates become involved, pulling him into increasingly dangerous situations.
The premise gives the drama a tense starting point, but its real interest lies in how the characters react when their plans stop working. Ji-soo is intelligent and disciplined, yet those qualities cannot protect him from panic, exploitation and the consequences of decisions he cannot easily reverse.
The series also challenges the assumption that a good student must have a stable life. Its young characters operate within pressures involving money, social status and limited opportunities, but the drama does not use those circumstances to excuse the harm they cause.
Why watch it: Extracurricular is a gripping Korean teen crime series for viewers who like morally complicated characters and stories about crime spiralling out of control.
10. The Glory
Genre: Revenge thriller, psychological drama
Although The Glory is not a conventional police procedural, crime and accountability sit at the centre of its story. Song Hye-kyo plays Moon Dong-eun, a woman who develops a long-term plan to confront the people responsible for the severe bullying she suffered during her school years.
As an adult, Dong-eun studies her former tormentors and looks for ways to expose the lies and privileges that have protected them. The drama builds tension through manipulation, secrets and strategic decisions rather than relying entirely on physical confrontations.
Its connection to crime storytelling comes from the way it explores abuse, cover-ups and the failure of powerful people to face consequences. The revenge plot is compelling because Dong-eun’s opponents are protected not only by their own choices but also by the social structures around them.
Why watch it: Pick The Glory if you want a Korean revenge thriller that explores wrongdoing, social privilege and the pursuit of accountability.
11. Mask Girl
Genre: Psychological thriller, crime, revenge
Mask Girl follows Kim Mo-mi, an office worker who feels invisible because of her appearance. Online, she performs behind a mask and experiences the attention she has struggled to find in everyday life. Her separate identities begin to collide, setting off a series of disturbing events.
The series uses crime and revenge to explore beauty standards, loneliness, obsession and public judgment. Its characters are complicated, and their decisions often produce consequences that cannot be undone. As the narrative shifts perspective, viewers are encouraged to reconsider how they understand the people at its centre.
Mask Girl is darker and more unsettling than a standard mystery series. Its emphasis is not on one detective steadily solving a case but on the human choices and social pressures that allow events to spiral into violence.
Why watch it: It is a distinctive choice for viewers seeking a dark Korean crime thriller with psychological tension, shifting perspectives and uncomfortable social commentary.
12. Beyond Evil
Genre: Psychological mystery, serial-crime investigation
Beyond Evil follows two detectives who investigate a series of disturbing crimes in a small town. As they pursue the truth, suspicion falls on people around them, including individuals whose histories are closely connected to earlier cases. The investigation becomes a test of trust as much as a search for evidence.
The series creates suspense through atmosphere, character psychology and carefully controlled revelations. Rather than revealing everything immediately, it encourages viewers to question what they think they know about the detectives, the suspects and the town itself.
Its focus on suspicion gives the story a different rhythm from action-oriented crime dramas. The tension comes from conversations, contradictions and the possibility that a familiar person may be hiding something important. For fans of slow-burn mysteries, that approach can be particularly rewarding.
Why watch it: Look for Beyond Evil if you enjoy Korean serial-killer mysteries, complex detective partnerships and suspense built around character secrets.
13. Flower of Evil
Genre: Crime thriller, mystery, melodrama
Flower of Evil follows a detective who begins to suspect that her husband, a man with whom she shares a family life, may be hiding a disturbing past. As she investigates a series of connected crimes, her professional instincts begin to conflict with her personal feelings.
The central relationship gives the crime story its emotional tension. The question is not simply who committed a crime, but whether the person a detective believes she knows can be trusted. Each new clue places the marriage under pressure and forces the characters to reconsider their understanding of one another.
The drama blends investigation with emotional suspense, making it a strong option for viewers who like crime stories where the consequences reach into family life. Its balance of mystery and melodrama may appeal especially to audiences who want character relationships alongside the case.
Why watch it: Choose Flower of Evil for a Korean crime mystery series combining investigation, secrets and relationship-driven suspense.
14. The Good Detective
Genre: Police procedural, murder mystery
The Good Detective follows detectives investigating serious crimes while dealing with the institutional and personal pressures surrounding their work. Its central appeal lies in the contrast between police officers who rely on experience and instinct and a system in which evidence, influence and public perception can complicate the pursuit of justice.
The series uses criminal cases to examine how investigations can be affected by mistakes, pressure and competing interests. It is more procedural than many revenge-focused Korean thrillers, making it a useful choice for viewers who want to spend time following detectives as they assemble a case.
The show also highlights the difference between believing someone is guilty and proving it. That tension is central to a good police drama, and it gives the characters room to question their assumptions as the evidence develops.
Why watch it: It is worth considering if you enjoy Korean police dramas on Netflix that focus on detective work, evidence and the pursuit of justice.
15. Somebody
Genre: Psychological crime thriller, serial murder mystery
Somebody centres on Kim Sum, a software developer connected to a dating app that becomes linked to a series of murders. As the investigation develops, digital relationships and private obsessions intersect with the danger surrounding the killer.
The series explores the uneasy relationship between technology and intimacy. Online platforms make it possible for people to connect, but they can also create opportunities for manipulation and concealment. The story uses that contradiction to build a disturbing atmosphere around its characters.
Rather than presenting a conventional detective-led procedural, Somebody focuses heavily on psychological tension and unsettling relationships. Its deliberate pacing and disturbing subject matter make it better suited to viewers who enjoy dark, character-driven mysteries than those looking for a straightforward action thriller.
Why watch it: Choose Somebody for a Korean psychological crime series about digital intimacy, obsession and the darker side of human behaviour.
16. Karma
Genre: Crime thriller, psychological suspense
Karma follows characters whose lives become entangled through a chain of criminal decisions and consequences. Its crime-driven premise explores how one person’s actions can create problems for others, bringing secrets and competing interests into the same increasingly dangerous situation.
The series is a suitable option for viewers who enjoy stories in which seemingly separate lives gradually connect. Rather than treating each decision as an isolated incident, the narrative builds tension through the way characters become trapped by choices they thought they could control.
For crime-drama fans, the appeal lies in watching the consequences accumulate and seeing how the characters respond when escape becomes more difficult. It fits naturally alongside Korean thrillers that prioritise moral compromise and psychological pressure over conventional detective work.
Why watch it: Consider Karma if you like Korean crime thrillers about interconnected lives, secrets and the consequences of bad decisions.
17. A Model Family
Genre: Crime thriller, family drama
A Model Family centres on an ordinary family man whose financial difficulties lead him into contact with a dangerous criminal organisation. What initially appears to be a desperate attempt to solve a personal problem becomes a far more complicated struggle involving drugs, deception and survival.
The series builds tension by placing family responsibilities alongside criminal risk. Its central character is not a professional criminal, and that difference shapes the decisions he makes when faced with people who have far more experience navigating the underworld.
The story explores how desperation can make dangerous opportunities appear reasonable. Each attempt to manage the situation creates new complications, and the family dimension gives the crime plot an additional layer of emotional pressure.
Why watch it: Choose A Model Family for a Korean family crime drama involving financial desperation, organised crime and increasingly risky decisions.
18. Mercy for None
Genre: Gangster thriller, revenge, action
Mercy for None is a strong choice for viewers who prefer Korean crime stories rooted in the underworld rather than police stations or courtrooms. The series follows a former gangster drawn back into violence, with the story built around criminal loyalties, revenge and the consequences of a dangerous past.
Its appeal is different from that of a traditional detective mystery. Instead of focusing on clues and suspects, it centres on rivalries and confrontations within a criminal environment. The atmosphere is harsher, and the tension comes from the knowledge that personal conflicts can quickly become violent.
For viewers who enjoy Korean noir and gangster stories, this kind of premise offers a more direct, action-led experience. It is worth checking the current Netflix listing in your region for availability and content information before starting.
Why watch it: Choose Mercy for None if you want a Korean gangster crime series built around revenge, criminal rivalries and hard-edged action.
Which Korean Crime Series on Netflix Should You Watch First?
The best starting point depends on the kind of crime story you enjoy. If you want action and undercover operations, begin with My Name or Narco-Saints. For a gangster story with intense fights, Bloodhounds and Mercy for None are stronger matches.
If your preference is for detectives and evidence, consider Signal, Stranger, Beyond Evil or The Good Detective. These series place more emphasis on investigations, suspicious behaviour and the process of uncovering the truth.
For darker psychological stories, A Killer Paradox, Mask Girl, Somebody and Flower of Evil offer morally complicated characters and mysteries built around secrets. Meanwhile, D.P., Juvenile Justice and The Glory explore wrongdoing and accountability through social and institutional conflicts rather than conventional detective work.
There is no single best Korean crime series for every viewer. The most satisfying choice is the one that matches your preferred pace, tone and type of mystery.

My Name delivers a personal revenge story with undercover action, Bloodhounds turns organised crime into a physical fight for survival, and Signal offers a mystery-driven approach to criminal investigation. Stranger is a strong choice for viewers interested in corruption and institutional power, while Beyond Evil rewards those who prefer psychological tension and layered detective work.
For a darker, character-driven experience, Mask Girl, Somebody and A Killer Paradox explore the unsettling motives behind criminal behaviour. If you want a crime story with a broader social perspective, D.P., Juvenile Justice and The Glory are also worth considering.
