RFA Bacchus (1915) was a stores freighter and distilling ship of the Royal Fleet Auxiliary. Built by William Hamilton and Company, of Port Glasgow for the Indo-China Steam Navigation Company and purchased by the Admiralty while on the stocks on 22 March 1915.
She was renamed RFA Bacchus II in May 1936 in order to free the name for a new ship. She was sunk as target on 15 November 1938 over the Hurd Deep, 10 miles off Alderney in the Channel Islands, by gunfire from the cruiser HMS Dunedin.
