Le Dieu Bleu () is a ballet in one act. Jean Cocteau and Federico de Madrazo y Ochoa wrote the story of the ballet. Reynaldo Hahn wrote the music. Michel Fokine designed the dances, and Léon Bakst designed the sets and costumes. The ballet was first performed in Paris at the Théâtre du Châtelet on 13 May 1912. It was a failure. Critics thought Nijinsky the dancer for whom the ballet was designed did more posing than dancing. Producer Sergei Diaghilev blamed Hahn's music for the failure. "Le Dieu Bleu" was staged three times in Paris in 1912 and three times in London in 1913. The ballet has not been revived.
