Kurt Westergaard (born July 13, 1935) is a Danish cartoonist who created the controversial cartoon of the Muslim prophet Muhammad wearing a bomb as a turban. This cartoon was the most contentious of the 12 Jyllands-Posten Muhammad cartoons, which received strong and sometimes violent reactions from Muslims and others worldwide.

On February 12, 2008, the Danish Security and Intelligence Service PET announced the arrest of three people—two Tunisians and one Dane of Moroccan origin—alleged to have been planning the murder of Westergaard.

Following the release of Geert Wilders' film Fitna, which used Westergaard's cartoon without permission, Westergaard made a cartoon depicting Wilders with a bomb and a sign which reads: "Danger! Freedom of expression".
