The 1988 Barambah state by-election was a by-election held on 16 April 1988 for the Queensland Legislative Assembly seat of Barambah, based in the town of Kingaroy. The by-election was triggered by the resignation of National MP and former premier Sir Joh Bjelke-Petersen. Until the by-election, the seat had been considered the Nationals' safest seat in Queensland.
