Bishop of Gloucester

The Bishop of Gloucester is the ordinary of the Church of England Diocese of Gloucester in the Province of Canterbury.

The diocese covers the County of Gloucestershire and part of the County of Worcestershire. The see's centre of governance is the City of Gloucester where the bishop's chair (cathedra) is located in the Cathedral Church of the Holy and Indivisible Trinity.

The bishop's residence is Bishopscourt, Gloucester; very near the Cathedral.

The office has been in existence since the foundation of the see in 1541 under King Henry VIII from part of the Diocese of Worcester. On 5 August 2014, Martyn Snow, the suffragan Bishop of Tewkesbury, became acting bishop of Gloucester.

On 26 March 2015, it was announced that Rachel Treweek was to become the next bishop of Gloucester (and the first woman to serve as a diocesan bishop in the Church of England); she legally became the bishop of Gloucester with the confirmation of her election on 15 June 2015.
