The Amazon class was a class of six screw sloops of wooden construction built for the Royal Navy between 1865 and 1866.
Designed by Edward Reed, the Royal Navy Director of Naval Construction, they were equipped with a ram bow. The hull was of wooden construction, but they were the first class of sloops to incorporate a form of composite construction; they had iron cross beams while retaining wooden framing.
Propulsion was provided by a two-cylinder horizontal single-expansion steam engine by Ravenhill, Salkeld & Company driving a single 15 ft (4.6 m) screw. Vestal and Nymphe were fitted with three-cylinder Maudslay engines.
The class was designed with two 7-inch (6½-ton) muzzle-loading rifled guns mounted on slides on centre-line pivots, and two 64-pounder muzzle-loading rifled guns on broadside trucks. Dryad, Nymphe and Vestal were rearmed in the early 1870s with an armament of nine 64-pounder muzzle-loading rifled guns, four each side and a centre-line pivot mount at the bow.
