Bournemouth East and Christchurch was a former United Kingdom Parliamentary constituency.
It returned one Member of Parliament, using the first past the post electoral system from the 1950 United Kingdom general election until the constituency was abolished in 1974.
The seat was based upon the eastern part of the seaside resort of Bournemouth and the neighbouring town of Christchurch, which were united for parliamentary purposes in 1950.
The County Borough of Bournemouth wards of Boscombe East, Boscombe West, King's Park, Queen's Park, Southbourne, and West Southbourne, and the Borough of Christchurch.
Under the Representation of the People Act 1918, Bournemouth became a single-member constituency, with the same boundaries as the then county borough.
