HMS Termagant (R89) was a T-class destroyer of the Royal Navy that saw service during the Second World War. She was built by William Denny and Brothers, of Dumbarton and launched on 22 March 1943. She was later converted to a Type 16 fast anti-submarine frigate, with the new pennant number F189. In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II. Termagant was sold for scrapping in 1965.
