The Grimsby class were a class of 13 sloops laid down between 1933 and 1940. Of these, eight were built in the United Kingdom for the Royal Navy, four in Australia for the Royal Australian Navy and one for the Royal Indian Navy. Main armament was initially two 4.7-inch (120 mm) guns for RN ships and three 4-inch (100 mm) for Australian ships, but armament varied considerably between ships, and was increased later.

Losses during World War II were Grimsby, Indus, Yarra, and Parramatta. Some survivors of this class served into the 1960s. One ship, Wellington, is preserved as the headquarters of the Honourable Company of Master Mariners.
