The Franco-Ottoman alliance or Franco-Turkish alliance was established in 1536 between Francis I, King of France and Suleiman I of the Ottoman Empire. The strategic and sometimes tactical alliance was one of the longest-lasting and most important foreign alliances of France, and was particularly influential during the Italian Wars. The Franco-Ottoman military alliance reached its peak with the Invasion of Corsica in 1553, during the reign of Henry II of France.

As the first non-ideological alliance in effect between a Christian and Muslim state, it attracted heavy controversy for its time and caused a scandal throughout Christendom. Carl Jacob Burckhardt (1947) called it "the sacrilegious union of the lily and the crescent". It lasted intermittently for more than two and a half centuries, until the Napoleonic campaign in Ottoman Egypt from 1798 to 1801.
