Martin Heton (Heaton) (1554–1609) was an English Bishop whose grandfather was the Lord Mayor of London.

His father George Heton was prominent in the London commercial world and as a church reformer.

[1][2][3] His mother Joanna was daughter of Martin Bowes, Lord Mayor of London in 1545.

[5] There is a story that Elizabeth I applied pressure to him, or his predecessor Richard Cox, over some land deals disadvantageous to the diocese, in a letter beginning “Proud prelate!”[7] But scholars from the nineteenth century onwards, for example Mandell Creighton, have considered the letter in question a hoax of the eighteenth century.

[8] A fat man, Heton was supposedly complimented by the king James I with the comment "Fat men are apt to make lean sermons; but yours are not lean, but larded with good learning.
