HMS Eclipse was a four-gun Cormorant-class first-class gunvessel launched in 1860 from the shipyard of J. Scott Russell & Co., Millwall.

She served on the Australia Station, took part in the Second Taranaki War, including contributing men to a naval brigade which attacked the Maori stronghold at Gate Pā.

The entire class were never satisfactory as gunvessels, partly due to their excessive draught, and Eclipse was broken up at Sheerness in 1867, only seven years after her launch.

The first 6 ships, including Eclipse, had a two-cylinder horizontal single-expansion steam engine provided by Robert Napier and Sons and rated at 200 nominal horsepower, driving a single screw.

[2] The main armament, which was principally intended for shore bombardment,[3] was originally designed with two 68-pounder and two 32-pounder muzzle-loading smoothbore guns.

[8] In September 1865 the Eclipse was engaged in transporting militia from Whanganui to Ōpōtiki as part of the East Cape War and in response to the Völkner Incident.
