The Dean of Peterborough is the head of the chapter at Peterborough Cathedral. On the Dissolution of Peterborough Abbey in 1539 and the abbey-church's refoundation as a cathedral for the new bishop and diocese of Peterborough, care for the abbey/cathedral church passed from an abbot to a dean. The current Dean of Peterborough is Chris Dalliston.

Peterborough Cathedral, properly the Cathedral Church of St Peter, St Paul and St Andrew, formerly St Peter's Abbey and also still known as St Peter's Cathedral in the United Kingdom, is the seat of the Anglican Bishop of Peterborough, dedicated to Saint Peter, Saint Paul, and Saint Andrew, whose statues look down from the three high gables of the famous West Front. Although it was founded in the Anglo-Saxon period, its architecture is mainly Norman, following a rebuilding in the 12th century. With Durham and Ely cathedrals, it is one of the most important 12th-century buildings in England to have remained largely intact, despite extensions and restoration.
