Chester Cathedral is a Church of England cathedral and the mother church of the Diocese of Chester. It is located in the city of Chester, Cheshire, England. The cathedral, formerly the abbey church of a Benedictine monastery dedicated to Saint Werburgh, is dedicated to Christ and the Blessed Virgin Mary. Since 1541, it has been the seat of the bishop of Chester.

The cathedral and former monastic buildings were extensively restored during the 19th century (amidst some controversy), and a free standing bell tower was added in the 20th century.
