Gilles de Caux de Montlebert, (c.1682, Ligneries – 17 September 1733, Bayeux) was an 18th-century French poet and playwright from Normandy.
A descendant of Pierre Corneille by his mother, he was controller of the king's farms. He served as nominees to président Hénault for the publication in 1716 of his tragedy Marius à Cirthe, to which he probably worked. His tragedy Lysimachus, completed by his son, was presented without success in 1737.
