The Archdeacons in the Diocese of Southwark are senior clergy in the Church of England in South London and Surrey. They currently include: the archdeacons of Southwark, of Reigate (formerly of Kingston-on-Thames) and of Lewisham & Greenwich (formerly of Lewisham), the Archdeacon of Croydon and the archdeacons of Wandsworth and of Lambeth. Each one has responsibility over a geographical area within the diocese.
The Diocese of Southwark was created on 1 May 1905 from two Diocese of Rochester archdeaconries: the archdeaconry of Southwark and the archdeaconry of Kingston-on-Thames. Parts of Surrey (from the dioceses of Winchester and of London) had first been transferred to Rochester diocese on 1 August 1877, and were organised into the Southwark archdeaconry on 3 May 1878. The Kingston archdeaconry was then created by Order in Council soon after, on 22 August 1879, by splitting the archdeaconry of Southwark. Not long after the diocese's creation, the new archdeaconry of Lewisham was created, on 6 March 1906, from part of the Southwark archdeaconry and part of the diocese not previously in an archdeaconry.
The archdeaconry of Wandsworth was created in 1973, the Croydon archdeaconry was moved from the Diocese of Canterbury on 1 January 1985. In 1986, the archdeaconry of Reigate was created from a renaming and reorganisation of the previous archdeaconry of Kingston-on-Thames and the archdeaconry of Lambeth was created from Southwark archdeaconry. Lewisham archdeaconry was renamed the Archdeaconry of Lewisham & Greenwich in 2008.
