What are registered Reddit users commonly called?

Registered Reddit users are commonly called “redditors.”

The term is Reddit’s long-established name for people who use the platform. It appears in Reddit’s own language as well as in journalism and everyday discussion, and it works as both a singular noun (“a redditor”) and a plural (“redditors”). The word is formed from “Reddit” with the familiar “-or” ending used for a person associated with an activity.

Redditors can submit posts, write comments, vote on content, join communities, and sometimes create or moderate subreddits. Not every visitor needs an account to read public material, so “redditor” most precisely refers to a person who participates as a Reddit user rather than simply someone who has viewed a page.

“Reddit user” is also correct and is often preferred in formal or audience-measurement language. However, among Reddit’s distinctive platform terms, “redditor” is the canonical nickname. It should not be confused with “poster,” which describes someone who submits a post, or “moderator,” which describes a user with management responsibilities in a community.
