Les Dominos roses (The Pink Dominos) is a three-act farce by Alfred Delacour and Alfred Hennequin. It concerns a plan by two wives to test their husbands' fidelity. At a masked ball at the Paris Opéra, each wife disguises herself in a pink domino – a hooded cloak with a mask – to woo the other's husband. The play was first produced at the Théâtre du Vaudeville, Paris on 17 April 1876 and ran for 127 performances. It was adapted for the West End and Broadway stages as The Pink Dominos, and later became the basis of a Viennese operetta (Der Opernball, 1898) and a musical comedy (To-Night's the Night, 1914). Background and first production In 1876 the Théâtre du Vaudeville emerged from a succession of short and unprofitable runs with the production of Le Procès Veauradieux by Alfred Delacour and Alfred Hennequin, which ran for 175 performances, at a time when a run of 100 performances was regarded as a success for a Parisian theatre. The authors' next piece for the house was Les Dominos roses. It opened on 17 April 1876 and ran for a total of 127 performances. The run was not continuous as, in common with other Paris theatres, the Vaudeville closed for several weeks during the height of each summer.

Each will attempt to woo the other's husband at a masked ball at the Opéra. With the aid of Hortense, Marguerite's maid, they concoct notes from supposed anonymous admirers to Georges and Paul, their spouses, inviting them to a rendezvous that evening. Both husbands fall for the ploy and invent plausible excuses for absenting themselves from home that night. Each meets his friend's wife, who is disguised under
