1949 Ipswich state by-election

The 1949 Ipswich state by-election was a by-election held on 10 September 1949 for the Queensland Legislative Assembly seat of Ipswich, based in the centre of Ipswich to the south-west of Brisbane. At the time of the election, the seat included the suburbs of Ipswich, Booval, Bundamba, Newtown, Silkstone, West Ipswich, Woodend and part of East Ipswich.

The by-election was triggered by the death of Labor member and Attorney-General of Queensland David Gledson on 14 May 1949. Gledson had held the seat since the 1915 election, with one brief interruption during the Great Depression. It was expected to be retained by the party.
