The Archdeacon of London is a senior ecclesiastical officer in the Church of England. She or he is responsible for one of two archdeaconries (the other is the Archdeaconry of Charing Cross) within the Two Cities (London and Westminster) episcopal area of the Diocese of London – that episcopal has no area bishop but is under the direct care of the diocesan Bishop of London.
Before the 20th century, the ancient London archdeaconry included parts of the East End as well as the City of London. The extent of the archdeaconry was reduced in 1912 (with the creation of the Archdeaconry of Hampstead) and in 1951 (with the creation of the Archdeaconry of Hackney) before more recent border changes limited the archdeaconry's recent area (until 2015/16) to that of the City of London.
