François Leclerc du Tremblay (1577 – 1638), also known as the Père Joseph, was a French capuchin monk, confident and agent of Cardinal Richelieu.

Because of his close connection to Richelieu, and his grey monkish robe, he was nicknamed the l'éminence grise ("grey eminence" — cardinals were referred to as eminences).

Grey Eminence is an English language biography by Aldous Huxley.
