St. Michael's was an electoral division of Manchester City Council which was represented from 1838 until 1950. It covered an area to the north of Manchester city centre including Newtown and a part of Collyhurst.
St. Michael's ward was one of the fifteen municipal wards created in 1838, when the Manchester Borough Council was granted a Charter of Incorporation under the provisions of the Municipal Corporations Act 1835.
Initially, the ward's boundaries corresponded with those of District No.2 (St. Michael's) of the Manchester Township, which covered the northernmost part of the township including the areas of Collyhurst and Monsall. Its original boundaries remained in place until 1885, when that part of the ward north of Collyhurst Street was transferred to the new Harpurhey ward. A further boundary revision took place in 1919 which had a relatively minor effect on the boundaries of St. Michael's ward. In 1950, the ward was abolished, and its area became part of the new Newtown ward.
From 1838 until 1885, the ward formed part of the Manchester Parliamentary constituency. From 1885 until 1918, it was part of the Manchester North Parliamentary constituency. From 1918 until 1950, it split between the Manchester Exchange and Manchester Platting Parliamentary constituencies. It briefly formed part of the Manchester Cheetham Parliamentary constituency from 1950 until its abolition.
