Clapham was a borough constituency in South London which returned one Member of Parliament (MP) to the House of Commons of the UK Parliament. It was created in time for the 1885 general election then altered in periodic national boundary reviews, principally in 1918, and abolished before the February 1974 general election. In its early years (until 1918) the seat was officially named Battersea and Clapham Parliamentary Borough: No. 2—The Clapham Division.
