St Chad's Church, sometimes known as St Chad on the Knavesmire, is a parish church in the South Bank area of York, in England.
In the early 20th century, the South Bank area fell within the parish of St Clement's Church, but it had a small mission church on South Bank Avenue. A church building on Campleshon Road was planned as a memorial to G. Argles, rector of St Clement's. The building was designed by Walter Brierley. Construction started in 1925, but was unfinished when Brierley died the following year. A vestry was added to the building in 1928, when the church was given its own parish. The church was finally completed by Francis Johnson in 1966, with only about half the original plan having been constructed. The building was Grade II listed in 2004.
The building is constructed of concrete, with brick facades, and a concrete roof vault. The main part of the church consists of a single space, serving as both nave and chancel, with side aisles, a narthex at the west end, with stairs leading to an organ gallery, and a chapel at the east end. There is a tower at the north-west; this incorporates a porch. The tower has a flat roof and has a brick niche containing a statue of Saint Chad. Externally, the building is divided into bays by full-height buttresses, and the walls are topped with a parapet of moulded brick. There is a priest's doorway at the south-east corner, with its own small tower. The windows are lancets, arranged at the west end in multiple tiers.
Inside, the nave and chancel are divided by a screen, with piers which support a piscina and aumbry. The pulpit is hexagonal and was constructed in 1940.
