Morestead was probably one of nine churches mentioned under Chilcomb in 1086. It belonged to the bishop and cathedral of Winchester.
The single-storey cottage-like structure abutting the W end of the church was built for the rector, who was not resident in the parish, in 1833; it was in use as a schoolroom by 1873. The church was restored, and a new chancel built, in 1873 (Hampshire Advertiser, 5 November 1873, 3). The architect was John Colson of Winchester and the style neo-Norman. At the same time, a W gallery was removed and the church was reseated.
