Bournemouth Borough Council was the local authority for Bournemouth in Dorset, England between 1974 and 2019. Prior to 1974 Bournemouth had been a county borough within Hampshire (being a county borough meant it was self-governing, being independent of Hampshire County Council). Under the Local Government Act 1972 Bournemouth became a non-metropolitan district within Dorset on 1 April 1974, with the same boundaries as the former county borough. On 1 April 1997 it became a unitary authority, taking over the functions previously provided for the area by Dorset County Council. In 2019 the council was abolished, merging with Christchurch and Poole to form Bournemouth, Christchurch and Poole.
