HMS Blankney was a Hunt-class destroyer of the Royal Navy and was the first and so far only warship to bear the name. She was laid down on 17 May 1940 at John Brown & Company, Clydebank, Scotland, launched on 19 December 1940 and commissioned on 11 April 1941.

The Hunt class was a class of escort destroyer of the Royal Navy. The first vessels were ordered early in 1939, and the class saw extensive service in the Second World War, particularly on the British east coast and Mediterranean convoys. They were named after British fox hunts. The modern Hunt-class GRP hulled mine countermeasure vessels maintain the Hunt names lineage in the Royal Navy.
