Paul-Philippe de Chaumont (1617 – 24 March 1697, in Paris) was a French prelate.
From an old family in Vexin where he was count of Chaumont, he was the son of a conseiller d'État, the author of many theological works as well as the king's librarian.
Becoming bishop of Dax in 1671, he resigned this post in 1684 so he would be freer to devote himself to studies, although continuing to preach.
Jean Chapelain said of him that "he had nothing lacking in his spirit, and had a great grasp of language and preached boldly and easily.
In 1693, he published a two-volume work entitled Réflexions sur le christianisme enseigné dans l'Église catholique.
