West Lothian by election, 1962

The West Lothian by-election, 1962 was a British parliamentary by-election held for the constituency of West Lothian in Scotland on 14 June 1962, following the death of its MP, John Taylor. It was important for two reasons: firstly, it saw the election of Tam Dalyell, who went on to become a long-standing and controversial MP; secondly, it saw a surprisingly strong showing by the Scottish National Party. The SNP candidate, William Wolfe, became their leader for several years.

Candidates from the Liberal and Conservative parties both lost their deposits. It was the first deposit lost by the Conservatives in Scotland since 1920.
