A Dáil by-election was held in the constituency of Mayo South in Ireland on Tuesday, 4 December 1945, to fill a vacancy in the 12th Dáil. It followed the resignation of Fianna Fáil TD Micheál Clery on 10 October 1945, after his appointment as county registrar of Dublin.
In 1945, Mayo South was a five seat constituency comprising the electoral areas of Castlebar, Claremorris and Westport in County Mayo.
The writ of election to fill the vacancy was agreed by the Dáil on 14 November 1945.
The by-election was won by the Clann na Talmhan candidate Bernard Commons.
Four other by-elections were held on the same day: in Clare, Dublin North-West, Kerry South and Wexford. Three by-elections were won by Fianna Fáil, one by Clann na Talmhan, and one by Labour.
