Tourville (S637) is a French nuclear attack submarine (SNA). After the Suffren and Duguay-Trouin, it is the third of six Suffren-class submarines in the Barracuda program, the French Navy's second-generation nuclear attack submarine. Like several French naval ships before her, she is named after Vice-Admiral and Marshal of France Anne Hilarion de Costentin de Tourville.

Construction began on 28 June 2011, at Cherbourg. She first set sail in July 2024. A few weeks later, on 11 September, the Red crew of the new submarine was formed at a ceremony at Fort Saint-Louis, Toulon. Just over two weeks after her departure, Tourville returned to Cherbourg for a technical intervention to apply a few corrective measures. The submarine was delivered to the navy and entered active service on 16 November 2024.
