The great thing about Netflix is there's always something to watch. Whether you want to marathon a TV show or check out a movie, you're almost guaranteed to find something that interests you. This is especially true of the streaming service's documentary selection. There are hundreds of documentaries available to stream on the platform, but probably the most popular are those that tell tales of the macabre. Which is why I've combed through all of them to uncover the most chilling documentaries on Netflix.

The documentaries listed here cover a wide range of subjects, including murder, missing persons cases, sex crimes, climate change, the food industry, politics, and animal abuse. But they all have one thing in common: Every single one of them will bother you at some level. And what's most disturbing is that these aren't just scary movies; they're documentaries. In other words, you can't just tell yourself "It's only a movie" after you watch one of them, because it's not only a movie. These are all documents of real events, which make them so much more frightening than anything even the most twisted minds in Hollywood can come up with. So if you're feeling brave, check out these 34 most chilling documentaries on Netflix.
