John King (died 30 March 1621) was the Bishop of London in the Church of England from 1611 to 1621.

After an early education at Westminster School, he matriculated at Christ Church, Oxford, in 1577, taught under Dr Thomas Holland, graduating B.A.

[1] In 1617, according to Samuel Purchas, while Pocahontas was in London King entertained her "with festival state and pomp beyond what I have seen in his greate hospitalitie afforded to other ladies".

Roman Catholic propagandists' claims that he converted to their church on his deathbed were denied in a sermon preached by his son, Henry King, the following November.

[1] King married Joan Freeman, and had five sons and four daughters:[3] There was a memorial brass to him at Old St Paul's Cathedral.
