HMS Hannibal was a 74-gun third-rate ship of the line of the Royal Navy, launched on 15 April 1786, named after the Carthaginian general Hannibal Barca. She is best known for having taken part in the Algeciras Campaign, and for having run aground during the First Battle of Algeciras on 5 July 1801, which resulted in her capture. She then served in the French Navy until she was broken up in 1824.
