The Dean of Southwell is the head (primus inter pares – first among equals) and chair of the chapter of canons, the ruling body of Southwell Minster. The dean and chapter are based at the Cathedral and Parish Church of the Blessed Virgin Mary in Southwell, Nottinghamshire. Before 2000 the post was designated as a provost, which was then the equivalent of a dean at most English cathedrals. The cathedral is the mother church of the Diocese of Southwell and Nottingham and seat of the Bishop of Southwell and Nottingham. The current dean is Nicola Sullivan.
