Bournemouth was a former United Kingdom Parliamentary constituency. The seat was created in 1918 and existed until it was abolished and split into two new seats in 1950. During the constituency's existence it was the most south-westerly seat in Hampshire (although the county boundary between Dorset and Hampshire was redrawn in 1974 so the town was transferred to Dorset).

Before 1918 the County Borough of Bournemouth formed part of the then parliamentary borough of Christchurch. Under the Representation of the People Act 1918 Bournemouth gained its own constituency, with the same boundaries as the then county borough.

The seat was bordered to the west by the constituency of Dorset East, while to the north was New Forest and Christchurch. The rest of the constituency bordered the English Channel.

In the 1950 redistribution, the Representation of the People Act 1948 provided for the division of Bournemouth (with the addition of the neighbouring town of Christchurch) into Bournemouth East and Christchurch & Bournemouth West.
