The Bavin ministry was the 44th ministry of the New South Wales Government, and was led by the 24th Premier, Thomas Bavin, in a Nationalist coalition with the Country Party, led by Ernest Buttenshaw.

Bavin was first elected to the New South Wales Legislative Assembly in 1917 and served continuously until 1935.

This ministry covers the period from 18 October 1927 until 3 November 1930[2] when the 1930 state election was held in the wake of the Great Depression resulting in the loss of the Coalition, with Lang regaining government as the third Lang ministry.

The composition of the ministry was announced by Premier Bavin on 18 October 1927 and covers the period up to 3 November 1930.
