St Michael's Church is a redundant Anglican church in Upton, Northamptonshire, England (). This was formerly a separate hamlet, and is now part of the town of Northampton. The church is recorded in the National Heritage List for England as a designated Grade I listed building, and is under the care of the Churches Conservation Trust. The church stands alongside the A45 road, adjacent to the grounds of the former Upton Hall. Early history St Michael's was built originally as a private chapel to the lord of the manor and it is thought that the present church was built between 1158 and 1189. Alterations were made to it between the 13th and 15th centuries, including the addition of the tower in the 14th century and a porch in 1594. The church was restored in 1892–93 by M. H. Holding. It was declared redundant on 1 January 1981, and was vested in the Churches Conservation Trust on 21 December 1988. Architecture Exterior The church is constructed in coursed limestone rubble. It has dressings in limestone and ironstone, and lead roofs. Its plan consists of a nave with a south porch, a chancel, and a west tower. The tower is set within the west end of the nave, and has two-light bell openings on each side, a battlemented parapet, and a pyramidal roof with a finial and a wrought iron weathervane. On the west side of the tower, facing Upton Hall, is a stair turret, above which is an octagonal clock face. Over the nave and chancel walls is a plain parapet. The east window in the chancel has three lights and Decorated tracery. In the north wall is a small lancet window and, to the west of this, a two-light Perpendicular window that was inserted in 1892. On the south side of the chancel is a round-headed priest's door, and to the west of this are two-light windows. In both the north and south walls of the nave are Norman round-headed doorways. Also in the north wall is a three-light Perpendicular window, also from 1892, and two single-light round-headed windows. In the south wall are two-light Perpendicular windows, and on each side of the roof of the porch is a small quatrefoil window. The porch has a Tudor arched doorway. On the east side of the porch is a circular window, and there is a rectangular window on its west side.
