The Jyllands-Posten Muhammad cartoons controversy (or Muhammad cartoons crisis) (Danish: Muhammedkrisen) began after the Danish newspaper Jyllands-Posten published 12 editorial cartoons on 30 September 2005, most of which depicted Muhammad, a principal figure of the religion of Islam.

The newspaper announced that this was an attempt to contribute to the debate about criticism of Islam and self-censorship. Muslim groups in Denmark complained, and the issue eventually led to protests around the world, including violent demonstrations and riots in some Muslim countries.
