Randall Thomas Davidson, 1st Baron Davidson of Lambeth, was an Anglican priest who was Archbishop of Canterbury from 1903 to 1928. He was the longest-serving holder of the office since the Reformation, and the first to retire from it.

The archbishop of Canterbury is the senior bishop and a principal leader of the Church of England, the ceremonial head of the worldwide Anglican Communion and the bishop of the Diocese of Canterbury. The current archbishop is Justin Welby, who was enthroned at Canterbury Cathedral on 21 March 2013. Welby is the 105th person to hold the position, as part of a line of succession going back to the "Apostle to the English" Augustine of Canterbury, who was sent to the island by the church in Rome in 597. Welby succeeded Rowan Williams.
