Saint-Satur (French pronunciation: [sɛ̃ satyʁ]) is a commune in the Cher department in central France.

Located in the area of Gaul settled by the powerful Celtic tribe, the Bituriges, or the "Kings of the World", and after their defeat at Bourges (Avaricum), part of Roman Aquitania.

Area transportation was improved by the construction of a suspension bridge at Saint-Thibault (1834), the Canal latéral à la Loire (1838) and later, the Bourges - Sancerre - Cosne-sur-Loire railroad line (1885).

During World War II, Saint-Satur, with Sancerre, was a regional command center for the French Resistance.

"Operation Spencer" in 1944 was to prevent the Germans from crossing the Loire River between Gien and Nevers and reinforcing troops in Brittany.
