Andrew Willet (1562 – 4 December 1621) was an English clergyman and controversialist. A prolific writer, he is known for his anti-papal works. His views were conforming and non-separatist, and he appeared as a witness against Edward Dering before the Star-chamber. Joseph Hall (who knew him well) eulogised Willet in Noah's Dove, and Thomas Fuller modelled 'the Controversial Divine' of his Holy State on him.
