HMS Hibernia was a 110-gun first-rate ship of the line of the Royal Navy. She was launched at Plymouth dockyard on 17 November 1804, and was the only ship built to her draught, designed by Sir John Henslow. On 11 January 1806, Hibernia capsized in the "Wembury River" — probably a reference to the River Yealm off Wembury, Devon, England — with the loss of 19 of her crew. She was later refloated, repaired, and returned to service.
