The third Dibbs ministry, the 27th ministry of the Colony of New South Wales, was led by Sir George Dibbs, leader of the Protectionist Party, following the 1891 New South Wales election, which saw the Labour Party win seats in the New South Wales Legislative Assembly and the balance of power. With no party having a majority, Sir Henry Parkes held on as Premier until October 1891 when he lost a vote in the Legislative Assembly, causing Parkes to resign as Premier and leader of the Free Trade Party. Dibbs formed the ministry on 23 October 1891, with Labour support, and comprised 10 ministers.
