Le postillon de Lonjumeau (The Coachman of Longjumeau) is an opéra-comique in three acts by Adolphe Adam to a French libretto by 'De Leuven and Brunswick' (pen names of Adolphe von Ribbing and Léon Lévy). It was first performed in Paris at the Opéra-Comique on October 13th, 1836.
The opera has become the most successful of Adam's works and the one by which he is best known outside his native France. The opera is known for the difficult aria "mes amis ecoutéz l'histoire" which has been referred to a test for tenors because of the demanding high D in the end of the aria.
The story is about a coachman who becomes a great opera singer after abandoning his wife on their wedding night to seek fame and fortune in Paris.
