Michel Le Quien (8 October 1661, Boulogne-sur-Mer – 12 March 1733, Paris) was a French historian and theologian.
Le Quien studied at Plessis College [fr], Paris, and at twenty entered the Dominican convent in Faubourg Saint-Germain, where he made his profession in 1682.
Excepting occasional short absences, Le Quien never left Paris.
At the time of his death he was librarian of the convent in Rue Saint-Honoré, a position which he had filled almost all his life, lending assistance to those who sought information on theology and ecclesiastical antiquity.
Under the supervision of Jacques Marsollier [fr] he mastered the classical languages, Arabic and Hebrew, to the detriment, it seems, of his mother tongue.
