Best True Crime Subreddits (November 2026)

Most true crime talk on Reddit happens in a few big places, but the smaller communities are where the specialists are. We checked the communities Reddit returns for “true crime”, kept the public, safe-for-work ones with at least 25,000 members that are still posting, and ranked the 6 that remain by size. Together they have 5.8M members.

How the true crime communities compare

Membership is concentrated: the three largest communities hold 98% of all members on this list, so most of the true crime conversation happens in a handful of places. Size and activity don't line up perfectly: r/TrueCrime has the most members, but r/TrueCrimeDiscussion gets the most new posts (about 18 a day). Per member, the liveliest is r/TrueCrimeMystery: 2.0 posts a day from 37.8K members — a smaller crowd, but an engaged one. The oldest is r/TrueCrime, founded in 2010; 2 of the 6 were started in the last five years, a sign the topic keeps splitting into new niches.

Choosing where to post

Competition for attention differs a lot: r/TrueCrimePodcasts has 975.5K members but only about 4.3 new posts a day — roughly one new post for every 226.9K members — while r/TrueCrimeDiscussion gets about 18 a day, one for every 74.4K. A strong, well-made post therefore has more room to be seen in r/TrueCrimePodcasts; r/TrueCrimeDiscussion is better when you want quick replies.

Before posting, sort a subreddit by “Top” for the past month: it shows in a minute what that community rewards. Always read the rules in the sidebar first — each community is run by its own volunteer moderators. Our guide to searching Reddit explains how to dig through any of these communities, and the subreddit info tool gives you the stats of one we don't list.
