Si j'étais roi is an opéra comique in three acts by Adolphe Adam. The libretto was written by Adolphe d'Ennery and Jules-Henri Brésil. It was first performed in Paris at the Théâtre Lyrique on 4 September 1852, opening with a dual cast to allow performance on successive evenings. The production was considered lavish, with expensive costumes and jewels being worn by the cast.
