John Ponet, sometimes spelled John Poynet, was an English Protestant churchman and controversial writer, the bishop of Winchester and Marian exile. He is now best known as a resistance theorist who made a sustained attack on the divine right of kings.

The Marian exiles were English Protestants who fled to continental Europe during the 1553–1558 reign of the Catholic monarchs Queen Mary I and King Philip. They settled chiefly in Protestant countries such as the Netherlands, Switzerland and Germany, and also in France, Italy and Poland.
