Saint Helen's Church, also often known as Saint Helen's Church and the Church of St Helena, is an Anglican church on the 445 ha island of Lundy, lying at the mouth of the Bristol Channel, 18 km off the north coast, and part of the county, of Devon in England. As there is no resident priest on the island, the church is only irregularly used to hold services, though it is open to visitors. It is part of the Diocese of Exeter.
