The 1937 Farnham by-election was held on 23 March 1937. The by-election was held due to the elevation to the peerage of the incumbent Conservative MP, Arthur Samuel. It was won by the Conservative candidate Godfrey Nicholson.^[1]

Peter Pain, a recently qualified barrister, contested the election for the Labour Party. Earlier in the decade, he had visited a Hitler Youth camp, and this experience convinced him that a war was inevitable, and that he should oppose Nazism by becoming a socialist.^[2]

Linton Thorp, who contested the election as an independent conservative, was a former Conservative MP who had left the party believing that some of its policies were too close to socialism. He stood with the support of the pro-Nazi Liberty Restoration League.^[3]
