Chelsea was a borough constituency, represented in the House of Commons of the Parliament of the United Kingdom.

In the 1918 redistribution of Parliamentary seats, the Metropolitan Borough of Chelsea (created as a local government unit in 1900) was represented by one MP.

In the redistribution which took effect in 1950, the then Brompton ward of the Metropolitan Borough of Kensington was added to the existing area of the constituency.

The constituency was included in a new London Borough of Kensington and Chelsea, although the Parliamentary boundaries were not altered immediately.

From the 1983 redistribution, Chelsea consisted of Abingdon, Brompton, Cheyne, Church, Courtfield, Earls Court, Hans Town, North Stanley, Redcliffe, Royal Hospital and South Stanley wards of Kensington and Chelsea.
