Les biches is a one-act ballet to music by Francis Poulenc, choreographed by Bronislava Nijinska and premiered by the Ballets Russes on 6 January 1924 at the Salle Garnier in Monte Carlo. Nijinska danced the central role of the Hostess. The ballet has no story, and depicts the random interactions of a group of mainly young people in a house party on a summer afternoon.
