The Théâtre de Paris is a theatre located at 15, rue Blanche in the 9th arrondissement of Paris. It includes a second smaller venue, the Petit Théâtre de Paris.

Ubu Roi is a play by French writer Alfred Jarry, then 23 years old. It was first performed in Paris in 1896, by Aurélien Lugné-Poe's Théâtre de l'Œuvre at the Nouveau-Théâtre. The production's single public performance baffled and offended audiences with its unruliness and obscenity. Considered to be a wild, bizarre and comic play, significant for the way it overturns cultural rules, norms and conventions, it is seen by 20th- and 21st-century scholars to have opened the door for what became known as modernism in the 20th century, and as a precursor to Dadaism, Surrealism and the Theatre of the Absurd.
