USS Buchanan (DD-131), named for Franklin Buchanan, was a Wickes-class destroyer in the United States Navy. Buchanan was transferred to the United Kingdom under the Destroyers for Bases Agreement in 1940 and served as HMS Campbeltown (I42). She was destroyed during the St. Nazaire Raid: at 1:34 on 28 March 1942, loaded with four tons of amatol explosive, the ship rammed the gates of the Forme Ecluse Louis Joubert dry dock. The ship exploded the following morning, ending the use of the dock for the rest of the war.
