HMS Chaplet was a C-class destroyer of the Royal Navy that was in service from August 1945, and which was scrapped in 1965.

The Royal Navy ordered Chaplet on 24 July 1942, one of eight "Ch" subclass "Intermediate" destroyers of the 1942 Programme.

She was laid down at the yard of Thornycroft, Woolston on 29 April 1943 and commissioned on 24 August 1945, too late for service in the Second World War.

She was given an interim modernisation in 1954, which saw her 'X' turret at the rear of the ship replaced by two Squid anti-submarine mortars.

On 22 May 1959, Chaplet collided with the Icelandic patrol boat Óðinn when on fishery protection duties.
