'The Barber of Seville', (Italian: Il barbiere di Siviglia), is an opera buffa in two acts by Gioachino Rossini with an Italian libretto by Cesare Sterbini. The libretto was based on Pierre Beaumarchais's French comedy Le Barbier de Séville (1775).

Rossini's Barber has proven to be one of the greatest masterpieces of comedy within music, and has been described as the opera buffa of all "opere buffe". After two hundred years, it remains a popular work.

Gioachino Antonio Rossini (29 February 1792 – 13 November 1868) was an Italian composer who gained fame for his 39 operas, although he also wrote many songs, some chamber music and piano pieces, and some sacred music. He set new standards for both comic and serious opera before retiring from large-scale composition while still in his thirties, at the height of his popularity.

Rossini began to compose by the age of 12 and was educated at music school in Bologna. His first opera was performed in Venice in 1810 when he was 18 years old. In 1815 he was engaged to write operas and manage theatres in Naples. He wrote 34 operas for the Italian stage that were performed in Venice, Milan, Ferrara, Naples and elsewhere; (such as the comic operas L'italiana in Algeri, Il barbiere di Siviglia (known in English as The Barber of Seville) and La Cenerentola, Otello, Tancredi and Semiramide. All of these attracted admiration for their innovation in melody, harmonic and instrumental colour, and dramatic form.
