HMS Trident was an iron paddle sloop built for the Royal Navy by Ditchburn & Mare in 1845 at Leamouth, London.

Trident's design was commissioned on 2 August 1842 for a steam yacht to replace HMS Black Eagle (previously Firebrand).

[1] She was originally intended to be fitted with a Maudslay side lever engine of 200 nominal horsepower, but received a Boulton, Watt & Co. two-cylinder oscillating steam engine with 70+3⁄4-inch (180 cm) diameter cylinders and 5-foot (1.5 m) stroke.

The engine was rated at 350 nominal horsepower and propelled her at a maximum speed of 9.5 knots (17.6 km/h) through a pair of paddle wheels.

[3] On 26 September 1849, she collided with HMS Dwarf in the Atlantic Ocean 60 nautical miles (110 km) south east of the Old Head of Kinsale, County Cork.
