A WikiProject (or Wikiproject) is the organization of a group of participants in a wiki established in order to achieve specific editing goals, or to achieve goals relating to a specific field of knowledge. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister projects such as Wiktionary, Wikiquote, and Wikisource. Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For example, in 2014 the Cochrane Collaboration announced that it had entered into a partnership with Wikipedia's WikiProject Medicine, "to improve the reliability and accessibility of Wikipedia medical information online".
