The 1943 Darwen by-election was a by-election held on 15 December 1943 for the British House of Commons constituency of Darwen in Lancashire.

Balfour was encouraged to stand by the Liberal Party 'Radical Action' group that believed in contesting by-elections and had achieved a good result at the 1943 Chippenham by-election.

However, the group was small and was unable to influence many party workers to give their support to her campaign.

Prescott held the seat until retiring in 1951.The result at the following General election;
