HMS Renown was a small two-decker 50-gun fourth-rate ship of the Royal Navy.

She belonged to the Portland class, designed in 1766 by John Williams, the Surveyor of the Navy, and was built under contract by Robert Fabian at Southampton.

Banks died on 18 June 1777, and command passed to Lieutenant George Dawson, posted captain in September 1777.

She took part in Admiral Richard Howe's notable action against the French fleet under the Comte d'Estaing on 11 August 1778.

She was fitted as a lazarette at Chatham Dockyard in March 1794, but was eventually broken up at Sheerness in December 1794.
