Mitcham and Morden is a constituency in Greater London represented in the House of Commons of the UK Parliament since 1997 by Siobhain McDonagh of the Labour Party.

The constituency was created in 1974 from the former seats of Mitcham and Merton & Morden.

Between 1974 and 1982 it was represented by Bruce Douglas-Mann who was elected as a Labour MP but defected in 1982 to the Social Democratic Party (SDP). Douglas-Mann was the sole SDP defector to resign his seat; he sought immediate re-election.

In the by-election Douglas-Mann triggered in May 1982, during the Falklands War, Angela Rumbold (Con) was elected. Rumbold's gain was the last time the Conservative Party would gain (as opposed to win) at a by-election until 22 May 2008 when Edward Timpson won the Crewe and Nantwich by-election, 2008.

At the 1997 General Election the seat was won by the Labour Party's Siobhain McDonagh. At the 2001, 2005 and 2010 General Elections, she was re-elected, in the latter election polling the 26th highest share of the vote for the party of the 631 seats contested.
