Ruy Blas is a tragic drama by Victor Hugo. It was the first play presented at the Théâtre de la Renaissance and opened on November 8, 1838. Though considered by many to be Hugo’s best drama, the play was initially met with only average success.

The name Théâtre de la Renaissance has been used successively for three distinct Parisian theatre companies. The first two companies, which were short-lived enterprises in the 19th century, used the Salle Ventadour, now an office building on the Rue Méhul in the 2nd arrondissement.
