Everybody Draw Mohammed Day was an event held on May 20, 2010 in support of free speech and freedom of artistic expression of those threatened by violence for drawing representations of the Islamic Prophet Muhammad. It began as a protest against censorship of an American television show, South Park, "201" by its distributor, Comedy Central, in response to death threats against some of those responsible for two segments broadcast in April 2010. Observance of the day began with a drawing posted on the Internet on April 20, 2010, accompanied by text suggesting that "everybody" create a drawing representing Muhammad, on May 20, 2010, as a protest against efforts to limit freedom of speech.

U.S. cartoonist Molly Norris of Seattle, Washington, created the artwork in reaction to Internet death threats that had been made against cartoonists Trey Parker and Matt Stone for depicting Muhammad in an episode of South Park. Depictions of Muhammad are explicitly forbidden by a few hadiths (sayings of and about Muhammad), though not by the Qur'an.^[1] Postings on RevolutionMuslim.com (under the pen name Abu Talha al-Amrikee; later identified as Zachary Adam Chesser) had said that Parker and Stone could wind up like Theo van Gogh, a Dutch filmmaker who was shot to death.^{[citation needed]}
