Fandom is a wiki hosting service and domain operated by Fandom, Inc. company, a for-profit Delaware company founded in October 2004 by Jimmy Wales and Angela Beesley. As of 2018, it is headed by Perkins Miller as CEO. Fandom uses MediaWiki, the open-source wiki software used by Wikipedia.

The company also runs the associated Fandom editorial project, offering pop-culture, and gaming news. Most Fandom wikis are hosted under the domain fandom.com, but some, especially those that focus on subjects other than media franchises, are hosted under Wikia.org.
