William Cosmo Gordon Lang, 1st Baron Lang of Lambeth, was a Scottish Anglican prelate who served as Archbishop of York (1908–1928) and Archbishop of Canterbury (1928–1942). His elevation to Archbishop of York, within 18 years of his ordination, was the most rapid in modern Church of England history. As Archbishop of Canterbury during the abdication crisis of 1936, he took a strong moral stance, his comments in a subsequent broadcast being widely condemned as uncharitable towards the departed king.

The archbishop of York is a senior bishop in the Church of England, second only to the archbishop of Canterbury. The archbishop is the diocesan bishop of the Diocese of York and the metropolitan bishop of the province of York, which covers the northern regions of England as well as the Isle of Man.
