HMS Witch (D89) was a Modified W-class destroyer of the British Royal Navy that saw service in World War II.

On 22 April 1940, Witch joined the light cruisers Galatea, Glasgow, and Sheffield, and the destroyers Campbell, Icarus, Impulsive, Ivanhoe, and Vansittart in Operation Sickle, in which the ships transported troops from Rosyth to Molde, Norway, to reinforce Allied forces at Andalsnes, with each destroyer carrying 60 troops; the ships arrived at Molde on 23 April 1940.

From 15 to 17 August 1941 Witch, Whitehall, and the Royal Netherlands Navy light cruiser HNLMS Jacob van Heemskerck escorted Convoy WS 10X from Liverpool to the Clyde.

[1] From 17 to 26 September 1941, Witch, Whitehall, Issac Sweers, Piorun, the destroyers Blankney, Laforey, Lightning, and Oribi, and the Polish Navy destroyer ORP Garland escorted Convoy WS 11X from the Clyde to Gibraltar in one of the preliminary moves of Operation Halberd, an effort to steam a resupply convoy through the Mediterranean Sea to Malta.

From 1 to 4 October 1941 she formed part of the local escort of Convoy WS 12 during its passage through the Western Approaches along with Cairo, Blankney, Whitehall, the destroyers Badsworth, Bradford, Brighton, Lancaster, Newark, Stanley, and Verity, and the Royal Canadian Navy destroyers Assiniboine and Saguenay, returning to the Clyde with those ships after detaching from the convoy.

From 13 to 15 December 1941, Witch, Badsworth, Vanquisher and the destroyers Beaufort and Volunteer provided the local escort for Convoy WS 14 in the Western Approaches, as usual returning to the Clyde upon completion of this duty.

[1] Witch continued her convoy escort duties in the North Atlantic into 1942 and was "adopted" by the civil community of Northwich, Cheshire, in March 1942 as a result of a Warship Week National Savings campaign.

[1] Later in February 1943, the Royal Navy selected Witch for transfer to Freetown, Sierra Leone, for service with local escort forces there.

[2] From 26 to 28 April 1943, she joined Malcolm and Wolverine in serving as local escort for Convoy WS 29 during the final leg of its voyage to Freetown.
