Other towns in the district included Redruth and Helston. The district also contained the Lizard Peninsula.
Kerrier is named after one of the ancient administrative Hundreds of Cornwall, Kerrier, which covered broadly the same area, but did not have a coast on the north.
The district was formed on 1 April 1974, as a merger of the borough of Helston, the urban district of Camborne-Redruth and Kerrier Rural District.
On 25 July 2007, Cornwall County Council's bid for unitary authority status was accepted by the government. It was abolished on 1 April 2009 as part of structural changes to local government in England.
Cornish musician Luke Vibert has released two albums and two 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.

The hundred of Kerrier was the name of one of ten ancient administrative shires of Cornwall, in the United Kingdom. Kerrier (sometimes Kirrier) is thought by Charles Thomas to be derived from an obsolete name (ker hyr = long fort) of Castle Pencaire on Tregonning Hill, Breage. It is likely that an even earlier name for the district was Predannack which has been displaced by the Lizard Peninsula as a geographical name.
