The Sirène-class submarines were a sub-class of the 600 Series built for the French Navy prior to World War II. There were four vessels in the class, built to a Loire-Simonot design. They were ordered in 1925 and completed by 1927. The four boats of the Sirène class saw action during the Second World War, from September 1939 until the French armistice in June 1940.

The Sirènes had a displacement of 609 tonnes (599 long tons) surfaced and 757 tonnes (745 long tons) submerged. They had an endurance of 3,500 nautical miles (6,500 km; 4,000 mi) at 7.5 knots (13.9 km/h; 8.6 mph), with a maximum surface speed of 13.5 knots (25.0 km/h; 15.5 mph), and a submerged speed of 7.5 knots (13.9 km/h; 8.6 mph). Their armament was seven torpedo tubes (3 forward, 2 midships, and 2 aft) with an outfit of 13 torpedoes.
