Webtoons changed horror. The vertical scroll format — where you slowly drag down, not knowing what's waiting at the bottom of the next swipe — creates a suspense mechanic that print comics and movies simply can't replicate. A horror artist will give you a long, empty stretch of black screen and let you keep dragging, your thumb moving slower and slower, until the thing they've been hiding finally slides into frame. Korean horror webtoon artists mastered this years ago, and nobody does the slow-drag scare better.
I'll be honest: I'm a coward about horror. I love it and I hate it in equal measure, and there are a couple of titles on this list I've never quite managed to finish at night. That cowardice is actually useful here, because it means I know exactly which of these will keep you up and which are safe to read with the lights off. The act of reading becomes part of the fear in this genre — you're the one pulling the horror toward you, one swipe at a time — and the best Korean horror webtoons understand that better than any other medium.
This is my honest list of the best horror webtoons, with content warnings flagged clearly and a note on where to read each one. Some are graphic; some are quietly psychological; one or two are barely horror at all and just want to give you the shivers without the scars. Read the warnings, then pick your poison.
Horror webtoons vary widely in intensity. I've noted content warnings for each recommendation — some are psychological and unsettling; others include graphic violence and body horror. Read the warnings before diving in.
What makes a webtoon scary
Horror is a genre about control — specifically, about taking yours away. A film does that with sound design and editing you can't pause; a haunted house does it with a corridor you have to walk down. A webtoon does it with the scroll. The artist decides how far you have to drag before the reveal, and that tiny delay between "I think something's coming" and actually seeing it is where the dread lives. Held empty space, an abrupt full-bleed panel, a face that appears just below the fold — these are the genre's basic tools, and Korean creators wield them with frightening precision.
The other thing that surprised me when I started reading horror webtoons is how often the scariest ones aren't supernatural at all. The most disturbing entries on this list are about human monsters — an abusive parent, a predatory system, the cruelty people are capable of when no one's watching. The ghosts and creatures are usually metaphors for something more ordinary and more frightening. That's why even the gory titles can leave you thinking rather than just flinching. Keep that in mind as you read: the swipe gets your heart rate up, but it's the people underneath that haunt you afterward.
The best horror webtoons on LINE Webtoon
A high school boy lives in terror of his father — a charming, respected CEO who is secretly a serial killer. When his father brings home a new victim, the boy must decide whether to help her escape or protect himself. One of the most acclaimed horror webtoons ever created. The psychological tension between a monstrous parent and a child who loves and fears him is extraordinary.
After losing his entire family, a reclusive teenager moves into a rundown apartment building — just as a mysterious plague begins transforming people into monsters based on their deepest desires. The residents must survive together. Adapted into a hit Netflix series, but the webtoon is darker and more visceral. The monster designs are extraordinary.
A detective investigates a series of seemingly unrelated deaths and discovers a terrifying pattern connecting them all to a supernatural entity. Slow-burn horror at its finest — the kind that builds dread episode by episode until the reveal hits you like a wall. The art style is distinctive and deeply unsettling.
A sweet, unconventionally attractive princess accidentally joins a club for "cursed" princesses — and discovers a community that actually supports each other. Less pure horror, more horror-comedy with a warm heart. One of the most beloved webtoons of recent years for its body-positive message wrapped in a delightfully creepy fairy-tale aesthetic.
A 820-year-old vampire noble awakens in modern South Korea and enrolls in high school while secret organisations pursue him. More action than horror, but the supernatural atmosphere, powerful villains, and gothic aesthetics place it firmly in the horror-adjacent space. One of the longest-running and most beloved webtoons ever published.
Monstrous beings appear out of nowhere to announce the exact time of a person's death — then return to drag them screaming to hell — and a religious movement rises to explain the terror. It's less about the creatures than about how fear reshapes a society, turning ordinary people into zealots and mobs. From the director of Train to Busan, and adapted into a Netflix series. Genuinely unsettling in a way that lingers.
A long-running anthology of standalone horror shorts — ghost stories, urban legends, twisted little parables — each one self-contained and built around a single nasty turn. The quality varies, as anthologies do, but the best entries are sharp, eerie, and over before you can catch your breath. A foundational Korean horror webtoon that helped define the format's jump-scare grammar.
A bullied teenager finds magical dice that can change anything about him, then gets pulled into a deadly competitive game with other dice-holders. It's more dark thriller than outright horror, but the escalating cruelty, body-altering stakes and creeping paranoia put it firmly in the horror-adjacent zone. A hugely popular long-form series with a real conclusion.
Not horror in the monster sense, but a different and quieter kind of terror: two children trying to survive across a war-ravaged landscape, where the dread comes from the simple, relentless question of whether they'll live. Drawn in stark monochrome, it's short, devastating, and the suspense is unbearable in the best way. The everyday horror of war made unforgettable.
A man wakes on a fishing boat with no memory, surrounded by strangers who insist they know him — and then people start dying. From the Bastard and Sweet Home team, it's a tight, claustrophobic psychological horror-mystery that keeps reshuffling what's real until the unsettling truth surfaces. Short, dense, and built to be reread once you know the ending.

Why Korean horror webtoons are different
- The scroll mechanic — Vertical scrolling creates suspense that panel-to-panel reading can't. The reveal is always one swipe away.
- Psychological over supernatural — The scariest Korean horror webtoons are usually about human monsters — abusive parents, predatory systems, broken people. The supernatural elements are metaphors.
- Free to read — Most horror webtoons are completely free on LINE Webtoon, with optional fast-pass for early access to new episodes.
- Adaptation pipeline — If a horror webtoon gets very popular, it usually becomes a K-drama or anime. Sweet Home, Bastard, and others have all made the jump.
Where to read these
The good news for nervous wallets is that a lot of horror is free. LINE WEBTOON — the global version of Korea's Naver Webtoon — hosts most of this list fully translated, including Bastard, Sweet Home, The Pale Horse, Cursed Princess Club, Noblesse, DICE, The Horizon and Pigpen, almost always on a free-with-ads or wait-for-the-next-episode basis. Naver Webtoon itself carries titles like Hellbound and Tales of the Unusual, though English availability shifts over time. Because completed horror series have usually been finished a while, most of their episodes are unlocked.
It's worth knowing the wider map, since licences move around. Tapas and Tappytoon both license Korean horror and dark thrillers into English, Lezhin Comics is the home of the most extreme, mature material, and KakaoPage is a major source of horror in Korea that increasingly reaches international readers through partner apps. Availability and pricing vary by country and month, so if a title isn't where I said it is, search the name inside your app of choice — I've avoided linking specific store pages because those links rot quickly.
Frequently asked questions
I scare easily — which one is safe to start with? Cursed Princess Club. It has the creepy fairy-tale look without genuine scares, and it's genuinely warm and funny underneath. If you want a real chill but nothing graphic, The Pale Horse builds dread through atmosphere rather than gore. Save Bastard and Sweet Home for when your nerve is up.
Are these horror webtoons free to read? Mostly, yes. LINE WEBTOON and Naver run a free-with-ads or wait-free model for most series, with an option to pay coins to skip ahead. The most extreme adults-only material on Lezhin tends to cost coins per chapter. Pricing and availability vary by region, so check inside the app.
Should I read the webtoon or watch the Netflix adaptation? Both, ideally — but if you only do one, the webtoon is usually the rawer, more intense version. Sweet Home and Hellbound were both reworked for their shows, and the original comics are darker and follow different paths. Read the webtoon first and the adaptation becomes a fascinating remix rather than a spoiler.
