The Cheerful-class gunboat was a class of twenty gunboats built for the Royal Navy in 1855 for use in the Crimean War.

The Cheerful class was designed by W.H. Walker (who also designed the preceding Dapper and Albacore classes). The ships were of particularly shallow draft for coastal bombardment in the shallow waters of the Baltic and Black Sea during the Crimean War.

One-cylinder horizontal direct-acting single-expansion steam engines built by John Penn and Sons, with two boilers, provided 20 nominal horsepower through a single screw, sufficient for 6.5 knots (12.0 km/h; 7.5 mph).

Ships of the class were armed with two 32-pounder smooth bore muzzle loading cannons.
