St Mary's Church (dedicated to St Mary the Virgin) is the Anglican parish church of the Hampden Park suburb of Eastbourne, a town and borough in the English county of East Sussex. Originally linked to the church at nearby Willingdon, it later became a separate parish church. The first building was destroyed by a bomb during World War II, and Edward Maufe was commissioned to design a replacement church; the hilltop building, finished in 1954, has been called "one of his most charming designs". English Heritage has listed it at Grade II for its architectural and historical importance.
