Le nabab is a three-act opéra comique by Fromental Halévy to a libretto by Eugène Scribe.
The title refers to a Nawab or Indian notable. The opera was the last collaboration of Scribe and Halévy, which began in 1835 with La Juive, Halévy's greatest success. It premiered in Paris on 1 September 1853.
The opera had 38 performances and appears not to have been revived.
