A by-election for the seat of Cheltenham in the South Australian House of Assembly was held on 9 February 2019.[1] The by-election was triggered by the parliamentary resignation of Labor Party MP and former Premier Jay Weatherill on 17 December 2018.[2] Labor candidate Joe Szakacs retained the seat with an increased margin.[3]
An Enfield by-election was held on the same day, as Weatherill's former deputy leader and Deputy Premier, John Rau, had also resigned from parliament.[4]
