USS Gendreau (DE-639) was a Buckley-class destroyer escort in the United States Navy. She was commissioned on 17 March 1944 and decommissioned on 13 March 1948. She served throughout the Pacific during World War II. Canadian-born Captain Elphege A. M. Gendreau (1888–1943) served as Force Surgeon of Battle Force and on the staff of Admiral Chester Nimitz, Commander in Chief, Pacific Fleet. Admiral Nimitz recommended that a ship be named in honor of the surgeon for his dedicated service, after Capt. Gendreau was killed in a dive-bombing attack while onboard USS LST 343 in the South Pacific 21 July 1943.
