The Bolte Ministry was the 58th Ministry of the Government of Victoria, and was led by Liberal Premier Sir Henry Bolte. It succeeded the Cain ministry on 7 June 1955, following the defeat of the Labor government at the 1955 election held ten days earlier. The ministry lasted over 17 years and was followed by the Hamer Ministry on 24 August 1972 after the resignation of Bolte from politics.
On 7 and 8 June 1955, the Governor, Sir Dallas Brooks, appointed the following ministers to the portfolios indicated. Some changes resulted from the departure of William Leggatt, who was appointed Agent-General for Victoria in London in February 1956, the death of Robert Whately the following month, and the appointment of Gordon McArthur as President of the Victorian Legislative Council. However, the ministry was stable from 1956 until its reconstitution after the 1961 election.
The list below is ordered by decreasing seniority within the Cabinet, as indicated by the Government Gazette and the Victorian Year Book.
