The Hecla class was a class of bomb vessels of the Royal Navy of the early 19th century. They were designed for use as bomb or mortar ships and were very heavily built. Eight ships were launched; all were converted for use as exploration or survey ships. Four ships of the class are known for the role they played in Arctic and Antarctic exploration.

HMS Hecla was a Royal Navy Hecla-class bomb vessel launched in 1815. Like many other bomb vessels, she was named for a volcano, in this case Hekla in southern Iceland. She served at the Bombardment of Algiers in 1816. Subsequently, she took part in three expeditions to the Arctic. She then served as a survey vessel on the coast of West Africa until she was sold in 1831. She became a merchantman and in 1834 a Greenland whaler. She was wrecked in 1840.
