USS Fanning (DD-385) was a Mahan-class destroyer, in the United States Navy named for Nathaniel Fanning. Her first action was during World War II, immediately following the 7 December 1941 attack on Pearl Harbor. Fanning continued to serve in the Pacific Theatre throughout the war, and was decommissioned 14 December 1945. She was one of the last Mahan-class destroyers. Fanning and USS Dunlap were built from the same basic Mahan design but slightly modified.
