The Cooper Ministry was a ministry of the Government of Queensland and was led by National Party Premier Russell Cooper and Deputy Premier Bill Gunn. It succeeded the Ahern Ministry on 25 September 1989 following a party-room ballot, and was in turn succeeded by the Goss Ministry on 7 December 1989 following the National government's defeat at the 1989 state election by the Labor Party, led by Wayne Goss. Seven of the outgoing ministry lost their seats at the election.
