Gilles de Caux de Montlebert

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.

Boileau praised one of his poems entitled L'Horloge de sable. He collaborated with L'Année littéraire by Fréron.
