1949 Prahran state by-election

The 1949 Prahran state by-election was held on 22 January 1949 to elect the member for Prahran in the Victorian Legislative Assembly, following the death of Labor Party MP Bill Quirk.

Frank Crean retained the seat for Labor, gaining a swing of 1% over the Liberal Party, which was serving in government at the time. Crean resigned two years later in 1951 to successfully contest the federal seat of Melbourne Ports, and he later served as Deputy Prime Minister for several months in 1975.

This was the second of three by-elections in Prahran held in a timeframe of six years, with by-elections also held in 1945 (where Quirk was elected) and 1951 (to replace Crean). This was also the final election contested by the original Victorian division of the Liberal Party, as the party ceased to exist in March 1949 when the new Liberal and Country Party (LCP) was formed.
