The Third Medhi ministry was the Cabinet of Assam headed by Chief Minister of Assam Bishnuram Medhi. The Ministry lasted from 22 April 1957 to 27 December 1957.
On 22 April, the new cabinet was sworn in at Raj Bhavan in Shillong. It originally consisted of nine ministers (including Medhi) and seven deputy ministers. The four newcomers to the cabinet were Debeswar Sarma, K. P. Tripathi, Moinul Huq Chaudhury, and Chatra Singh Teron.
Medhi appointed Usha Barthakur, marking the first time a woman served in an Assam ministry since 23 March 1957. However, Barthakur would leave office following Medhi's resignation on 27 December 1957.
