St. Mary's Church, Westwood is a parish church in the Church of England in Jacksdale, Nottinghamshire.

The church was built in 1898 to the designs of the architect Percy Heylyn Currey to serve the expanding mining villages.

Francis Cowper, 7th Earl Cowper provided the land and James Oakes provided funding.

Although the church is in Jacksdale, it takes its name from the village of Westwood where services were held at the village school for 30 years before the church was built.
