The Best Korean Horror Movies to Watch Online in 2021

Okay, before we even jump into this list of the 20 best Korean horror movies to stream, I need to make something clear — these are not in order. There’s just no way I could actually rank these from best to worst because they are all really different. Instead, I’m just sharing some of the titles that I have enjoyed. 

I will say, though, that a few of these really stand out. Train to Busan was such a unique take on zombies, as was #Alive. Our whole house was freaking out when we watched Gonjiam: Haunted Asylum, so save that for a night when you really want a good scare. We’re hoping to get to South Korea sometime soon, and visit some of these spooky locations!

1. Train to Busan (2016)

  • Horror Sub-Genre: Zombie, Action
  • Starring: Gong Yoo, Ma Dong-seok, Jung Yu-mi

If you’re a zombie fan, you really do not want to miss Train to Busan. The story follows a father and his young daughter as they take the high-speed train from Seoul to Busan. As they leave the station, though, zombies suddenly spring into action and make it onto the train. You can only imagine how crazy (and sad!) things get as they try to make it to their destination.

2. #Alive (2020)

  • Horror Sub-Genre: Zombie, Drama
  • Starring: Ah-In Yoo, Shin-Hye Park, Bae-soo Jeon 

The plot revolves around a video game live streamer’s struggle to survive after a zombie outbreak hits Seoul. Forced to stay alone in his apartment, he must come up with ways to stay fed and hydrated while trying to find a way to escape. Some might argue about this being on our list of the best Korean horror movies, but we really liked it!

4. Seoul Station (2016)

  • Horror Sub-Genre: Zombie, Animation
  • Starring: Ryu Seung-ryong, Shim Eun-kyung, Lee Joon

If you enjoy Train to Busan, you may also like Seoul Station. The animated film is one of the best Korean horror movies and is a prequel to the zombie flick. Don’t let the cartoonish imagery fool you, though. It’s still pretty horrifying! In fact, you might actually think it’s even scarier than Train to Busan as it explores the darker side of human nature.

5. A Tale of Two Sisters (2003)

  • Horror Sub-Genre: Mystery
  • Starring: Im Soo-jung, Moon Geun-young, Yum Jung-ah

After receiving treatment at a mental institution, Su-mi returns to her family’s isolated country home. While glad to be reunited with her younger sister, Su-yeon, Su-mi starts to suspect that the girl is being abused by her stepmother. On top of that, Su-mi is also having nightmares about her mother’s ghost. This movie is a little older, but it’s definitely worth watching!

6. The Piper (2015)

  • Horror Sub-Genre: Mystery, Thriller
  • Starring: Ryu Seung-ryong, Lee Sung-min, Chun Woo-hee, Lee Joon

Familiar with the story of the Pied Piper of Hamelin? If so, you may appreciate this creepier retelling of the popular fairytale. The film follows a flute player and his young son who stop in a remote village on their way to Seoul some time after the Korean War. The locals are eager to let the man help him rid the village of a rat infestation, but we’re reminded of why we should never be so quick to trust strangers.

Set in an abandoned psychiatric hospital, Gonjiam: Haunted Asylum follows a group of YouTubers who are striving to pull in a million viewers. As such, the whole film is meant to look like found footage as they push through some pretty scary moments to try to meet their goal. Want to be even more creeped out? It’s based on the Gonjiam Psychiatric Hospital in Gwangju. As they mention in the movie, CNN even lists it as one the 10 freakiest places in the world

10. The Host (2006)

  • Horror Sub-Genre: Monster

You might be reminded of Godzilla (one of my absolute favorite monsters!) while watching The Host. The plot unfolds after a lizard-like monster emerges from the Han River and heads straight to Seoul. One father and his siblings must battle the creature after it takes his daughter. Fans of Parasite and Snowpiercer might be particularly interested in this early work from director, Bong Jooh-ho.
