Philippe Le Sueur, sieur de Petiville (31 March 1607 – 24 December 1657), was a Neo-Latin French poet.
Upon returning to his homeland at the age of twenty-six, he was appointed a counselor at the Parliament of Normandy, a position which, according to the testimony of Pierre-Daniel Huet, he held with great integrity.
A poet and a scholar, Le Sueur cultivated Latin poetry with some success, and he was among the distinguished people who composed the Académie des Sciences, Arts et Belles-Lettres de Caen at the time of its founding.
They had two children and one grandson, Jacques, Sieur de Cairon, born in 1673 and still reported as a Huguenot in 1749.
The introductory parts of Geographiæ sacræ pars prior (Phaleg, de S. Bochart, Cadomi, 1646) incorporate some of his Latin verses.
