Citation needed, most commonly rendered as Citation needed, is a common editorial remark on Wikipedia, which has become used to refer to Wikipedia in wider popular culture.


To ensure that all the Wiki's content is verifiable, anyone may question an un-cited claim by inserting a "Citation needed" tag.

  • Exercise caution before relying upon unsourced claims.
  • If you can provide a reliable source for the claim, please be bold and replace or ask an admin to replace the "Citation needed" tag with enough information to locate the source. You may leave the copyediting to someone else, or learn more about citing sources.
  • If someone tagged your contributions with Citation needed and you disagree, discuss the matter on the article's discussion page.
  • Controversial, poorly-sourced claims in biographies of living people should be deleted immediately.
