HMT Elk was a 181-ton former fishing trawler built in 1902. She served in the Royal Navy in World War II, until sunk without loss of life having hit a mine off Plymouth in November 1940.

Elk was built by Cook, Welton & Gemmell at Beverley, Yorkshire, launched on 21 August 1902, and first operated from Grimsby. During World War I she was hired by the Admiralty and served as a minesweeper from 1914 until 1918. She was then operated commercially by various owners at Grimsby, Hakin, and Plymouth. Elk was hired by the Admiralty in November 1939 to serve as a danlayer (laying buoys in channels cleared by minesweepers) and was armed with one 6-pounder gun. HMT Elk was sunk by a mine south-east of Penlee Point, Plymouth on 27 November 1940. There were no casualties.

The Elk was re-discovered by divers in 1981 upright on a sandy bed at 50°17.800′N 4°10.600′W / 50.296667°N 4.176667°W / 50.296667; -4.176667 in 30 metres (98 ft) of water with a drop-off in excess of 40 metres (130 ft).
