The 7.65×20mm Longue (also known as 7.65mm French Longue, 7.65 mm Long, 7.65mm MAS, 7.65×20mm, and 7.65L) was a straight, rimless cartridge used in the French Modele 1935 pistols, as well as the MAS-38 submachine gun.

The US .30 Pedersen cartridge (or .30-18 Automatic) used in the Pedersen device was the basis for the 7.65×20mm Longue, the dimensions being identical. The French military were introduced to the cartridge when the US demonstrated the Pedersen device after the end of World War I in LeMans and again when John Browning exhibited a carbine in the same caliber in 1920.

7.65×20mm Longue ammunition was manufactured in quantity from approximately 1935 to 1960.
