The Wigan by-election of 12 June 1958 was held after the death of the incumbent Labour Member of Parliament (MP) Ronald Williams. The by-election was contested by three candidates: Alan Fitch (Labour), John Hodgson (Conservative), and Michael Weaver (Communist). The result was a hold for the Labour Party, with Fitch gaining 71% of the vote on a 6.2% swing from the Conservative Party.
