Le train bleu is a one-act ballet choreographed by Bronislava Nijinska to music by Darius Milhaud for Serge Diaghilev's Ballets Russes, based on a scenario by Jean Cocteau.

The ballet is set on the fashionable French Riviera and has a sporting theme, with swimmers, tennis players, and weight lifters.

Henri Laurens supplied a Cubist beach scene and Coco Chanel[1][2] outfitted the cast in sportswear.

The curtain was painted after Deux femmes courant sur la plage, a 1922 work by Pablo Picasso.

The ballet was first performed on 20 June 1924 at the Théâtre des Champs-Élysées in Paris, with Nijinska, who played a tennis player based on Suzanne Lenglen, Lydia Sokolova, Anton Dolin and Leon Woizikovsky in the leading roles.
