The Second Mitchell Ministry was the 17th Ministry of the Government of Western Australia and was led by Nationalist Premier Sir James Mitchell. It succeeded the First Collier Ministry on 23 April 1930, following the defeat of the Labor government at the 1930 election on 26 March. The ministry served at the height of the Great Depression. During its term, Norbert Keenan resigned from the cabinet following a dispute with the Premier, and Thomas Davy, widely touted as a future party leader, died.
