The Philomel-class gunvessel was a class of wooden-hulled screw-driven second-class gunvessels built for the Royal Navy between 1859 and 1867, of which 26 were ordered but only 20 completed. They had a mixed history, with some serving for as little as 5 years, and others surviving into the 1880s. Two of the class were sold and used as Arctic exploration vessels, both eventually being lost in the ice.
