HMS Revenge was a 74-gun third-rate ship of the line of the Royal Navy, launched on 13 April 1805. Sir John Henslow designed her as one of the large class 74s; she was the only ship built to her draught. As a large 74, she carried 24-pounder guns on her upper gun deck, rather than the 18-pounder guns found on the middling and common class 74s.
