The Bishop of Southwell and Nottingham is the diocesan bishop of the Church of England Diocese of Southwell and Nottingham in the Province of York.
The diocese covers 847 square miles (2,190 km2) including the whole of Nottinghamshire and a small area of South Yorkshire. The see is in the town of Southwell where the seat is located at the Cathedral and Collegiate Church of the Blessed Virgin Mary (also known as Southwell Minster), which was elevated to cathedral status in 1884.
The diocese was created in 1884 under Queen Victoria. Until 2005 it was known simply by the name "Southwell"; Nottingham was added to the title in that year. The current bishop is Paul Williams, whose election was confirmed on 11 May 2015.
There are 314 church buildings in the Diocese.
The bishop is assisted by the suffragan Bishop of Sherwood, the current incumbent being Tony Porter.
