Robert Guérard (1641 – 2 January 1715) was a French Benedictine scholar of the Congregation of St. Maur.
For some time, he collaborated at Saint-Denys in the Maurist edition of the works of Augustine of Hippo.
In 1675, however, he had to leave Saint-Denys by order of Louis XIV, who wrongly suspected him of having had a hand in the publication of L'Abbé commendataire, a work which severely criticized the practice of holding and bestowing abbeys, etc., in commendam.
His superior sent him to the monastery of Notre Dame at Ambronay, in the Diocese of Belley.
After a year of exile, he was recalled, and spent the rest of his life successively at Fécamp Abbey and at the monastery of Saint-Ouen, where he died.
