USS Killen (DD-593), a Fletcher-class destroyer, was a ship of the United States Navy named for Edward Killen, who served in the First Barbary War. Killen volunteered for Lieutenant Stephen Decatur's daring 1804 expedition into Tripoli Harbor to destroy Philadelphia, a United States frigate captured by Tripolitan pirates. Killen was launched on 10 January 1943, by the Puget Sound Navy Yard, Bremerton, Washington; sponsored by Mrs. Inez Cowdrey; and commissioned on 4 May 1944, Commander H. G. Corey in command.
