Farnham was a constituency covering the south-westernmost and various western parts of Surrey for the House of Commons of the UK Parliament, 1918—1983. Its main successor was South West Surrey. The seat was formed with north-eastern territory including Woking from Chertsey in 1918 and shed the Woking area to form its own seat in 1950. It elected one Member of Parliament (MP). During its 65-year span its voters elected three Conservatives successively.
