Bermondsey was a borough constituency centred on the Bermondsey district of South London, England. It returned one Member of Parliament (MP) to the House of Commons of the Parliament of the United Kingdom. Elections were held using the first-past-the-post voting system.

The constituency was created for the 1885 general election and abolished for the 1918 general election, when almost all its territory was represented by the new Bermondsey West and a very small amount going into the existing Rotherhithe constituency.

A new Bermondsey constituency was created for the 1950 general election including Rotherhithe, was and abolished for the 1983 election, when it was largely replaced by the new Southwark and Bermondsey constituency.

The 1983 by-election was one of the most bitterly contested by-elections in the United Kingdom as it involved Bob Mellish, the retired Labour MP, running a highly personal and homophobic campaign against the Labour candidate, Peter Tatchell. The result was the election of Simon Hughes as a Liberal in a former Labour stronghold.

1950–1974: The Metropolitan Borough of Bermondsey.

1974–1983: The London Borough of Southwark wards of Abbey, Bricklayers, Browning, Cathedral, Chaucer, Dockyard, Riverside, and Rotherhithe.^[1]
