Pierre Lacotte was a French ballet dancer, choreographer, teacher, and company director. He specialised in the reconstruction of lost choreographies of romantic ballets.

La Sylphide is a romantic ballet in two acts. There were two versions of the ballet; the original choreographed by Filippo Taglioni in 1832, and a second version choreographed by August Bournonville in 1836. Bournonville's is the only version known to have survived and is one of the world's oldest surviving ballets.
