Pierre Casimir Hyppolyte Lachambeaudie (16 December 1806 – 7 July 1872) was a 19th-century French fabulist, poet, goguettier and chansonnier, as well as a follower of Saint-Simonianism.

His fables were crowned twice by the Académie française.

He is buried at cimetière du Père-Lachaise in Paris (48th division).

The place Lachambeaudie in the 12th arrondissement of Paris was named after him in 1905.
