L'Hôtel du libre échange (French for Free-Exchange Hotel) is a comedy written by the French playwrights Georges Feydeau and Maurice Desvallières in 1894. The play takes place in Paris in the 19th century and follows two Parisian households and their friends over the course of two days. The play has three acts: Acts One and Three take place in Monsieur Pinglet's office, while Act Two takes place in Hôtel du Libre Échange, a small Parisian hotel. The play has been translated into several other languages.
The vaudeville was first performed at the Théâtre des Nouveautés, Paris, on 5 December 1894. The Annales du Théâtre et de la Musique, noting that the laughter reverberated inside and out of the auditorium, said that a reviewer could only laugh and applaud rather than criticise. Another critic, predicting a long run, wrote that he and his colleagues would not be needed at the Nouveautés in their professional capacities for a year or so but would know where to come if they wanted to laugh. The play ran for 371 performances.
