St Mary's Church is an Anglican church in the village of Slaugham in Mid Sussex, one of seven local government districts in the English county of West Sussex. The 12th- and 13th-century church, restored in the Victorian era, serves a large rural area of the Sussex Weald, covering three villages as well as the ancient settlement of Slaugham. It also controlled the church in the market town of Crawley—now one of the area's largest towns—for the first few centuries of its existence. A locally important family built a private chapel in the church in the 17th century, and a series of memorials to deceased family members are considered to be excellent examples of their type. English Heritage has listed the building at Grade II* for its architectural and historical importance.

St John the Baptist's Church is an Anglican church in Crawley, West Sussex, England. It is the parish church of Crawley, and is the oldest building in the town centre, dating from the 1250—although many alterations have been made since, and only one wall remains of the ancient building. In September 2017, a team from St Peter's Brighton began a new phase in the life of St John's Crawley. St John's offer a variety of services, traditional and informal, and contemporary services.
