The Hunter class was a class of two sloops of wooden construction built for the Royal Navy between 1755 and 1756.

Both were built by contract with commercial builders to a common design prepared by Thomas Slade, the Surveyor of the Navy.

Both were ordered on 5 August 1755, and contracts with the builders were agreed on 8 August.

They were two-masted (snow-rigged) vessels, although the Hunter was built with a 'pink' or very narrow stern (and a keel 3 feet longer than the original design), while her sister Viper had a traditional 'square' stern.

Hunter was captured by two American privateers off Boston on 23 November 1775, but was retaken by HMS Greyhound the following day.
