A by-election for the seat of Lowan in the Victorian Legislative Assembly was held on Saturday 4 November 1944. The election was triggered by the notification of the death of Country Party member Hamilton Lamb on 7 December 1943. Lamb was a prisoner of war on the Burma Railway at the time of the June 1943 state election, and he had been re-elected as MLA for Lowan is unopposed in his absence. He died on 7 December, but official notification of his death in Thailand was not received in Australia until 1 September 1944, nearly nine months later.

• John Matthew Tripovich (Labor), an assistant station master from Nhill
• Wilfred John Mibus (United Country), a farmer and grazier from Horsham
