On 29 November 2012, a by-election was held for the UK House of Commons constituency of Croydon North in the London Borough of Croydon. The by-election was caused by the death of its Member of Parliament Malcolm Wicks. It took place on the same day as by-elections in Middlesbrough and Rotherham. The by-election was won by Steve Reed of the Labour Party.

Malcolm Hunt Wicks was a British Labour Party politician and academic specialising in social policy. He was a member of parliament (MP) from 1992, first for Croydon North West and then for Croydon North, until his death in 2012.
