Kerrier (Cornish: Keryer) was a local government district in Cornwall, England, United Kingdom.

It was the most southerly district in the United Kingdom, other than the Isles of Scilly.

On 25 July 2007, Cornwall County Council's bid for unitary authority status was accepted by the government.

Kerrier District Council was abolished on 1 April 2009 as part of structural changes to local government in England.

Cornish musician Luke Vibert has released a number of albums and singles under the alias Kerrier District, as a nod to New York musicians Metro Area and a tribute to the place where he grew up.
