The Chalk Ministry was the 38th ministry of the Government of Queensland and was led by Liberal Party Premier Gordon Chalk. It succeeded the Pizzey Ministry on 1 August 1968 following Pizzey's unexpected death on 31 July, and was sworn in as a temporary measure until the Country Party, the dominant coalition partner, could elect a leader. It did so and on 8 August 1968, Joh Bjelke-Petersen became leader and Premier of Queensland, and the Bjelke-Petersen Ministry was constituted.
