The second HMS Exmoor (L08), ex-HMS Burton, was a Hunt-class destroyer of the Royal Navy in commission from 1941 to 1945. She was a member of the second subgroup of the class, and saw service during much of World War II. She later served in the Royal Danish Navy as HDMS Valdemar Sejr .

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.
