Philippe de Courcillon, Marquis de Dangeau (21 September 1638 – 9 September 1720) was a French officer and author.
Born in Dangeau, he is most remembered for keeping a diary from 1684 until the year of his death.
These Memoirs, which, as Saint-Simon said "of an insipidity to make you sick", contain many facts about the reign of Louis XIV.
