The media have covered controversial events and scandals related to Wikipedia and its funding organization, the Wikimedia Foundation (WMF). Wikipedia's open-editing model, under which anyone can edit most articles, has led to concerns, such as the quality of writing, the amount of vandalism, and the accuracy of information on the project.

Since the launch of Wikipedia in 2001, several controversies have occurred. The hoax raised questions about the reliability of Wikipedia and other websites with user-generated content.

John Seigenthaler, an American journalist, was the subject of a defamatory Wikipedia hoax article in May 2005.
