Subreddit

A subreddit is an individual community or forum within Reddit dedicated to a specific topic, interest, or purpose, identified by the prefix "r/" followed by its name (for example, r/news or r/AskReddit). Each subreddit has its own posts, comment threads, rules, styling, and volunteer moderators who set and enforce local norms on top of Reddit's site-wide policies. Anyone with an account can create a subreddit, subscribe to follow its content in their feed, and submit links, text posts, images, or other media for the community to discuss and vote on.

Subreddits are the fundamental organizing unit of Reddit and the reason the site describes itself as a network of communities. They range from massive default-style communities with tens of millions of members to tiny niche forums, and their independence gives each its own culture and moderation style. This decentralized structure is central to most Reddit controversies: because moderators control their own communities, conflicts over rules, removals, moderator conduct, and platform policy frequently play out at the subreddit level—most visibly during the 2023 API protests, when thousands of subreddits set themselves to private or restricted in coordinated blackouts.
