The Commandant Rivière class was a class of frigates built for the French Navy in the late 1950s and early 1960s. Labeled "aviso-escorteur" (fr: "sloop-escort"), they were designed to perform the role of overseas patrol in peacetime and anti-submarine escort in wartime. This vessel class is named after the French Navy officer Henri Rivière (1827–1883).

Four similar ships were built for the Portuguese Navy as the João Belo class.
