The Cuckoo class was a class of twelve 4-gun schooners of the Royal Navy, built by contract in English shipyards during the Napoleonic War. They followed the design of the Bermuda-designed and built Ballahoo-class schooners, and more particularly, that of Haddock. The Admiralty ordered all twelve vessels on 11 December 1805. A number of different builders in different yards built them, with all launching in 1806.
