The Cathedral Church of St Peter and St Paul, Sheffield, also known as Sheffield Cathedral, is the cathedral church for the Church of England diocese of Sheffield, England. Originally a parish church, it was elevated to cathedral status when the diocese was created in 1914. 

Construction of the earliest section of the cathedral dates back to c. 1200, with the newest construction completed in 1966; the building is an unusual mixture of medieval and modern architecture. Most recently, the cathedral underwent an interior and exterior refurbishment in 2013–2014.
