HMS Peterel was a Rosario-class sloop of the Royal Navy. Peterel served three commissions as a warship, on the North America and West Indies Station, the Cape of Good Hope Station and the Pacific Station. In 1877 she became a lightship marking the wreck of HMS Vanguard, then in 1885 she was converted into a coal depot before finally being sold in 1901, the longest lived of her class.
