The Barber of Seville, or The Useless Precaution (Italian: Il barbiere di Siviglia, ossia L'inutile precauzione [il barˈbjɛːre di siˈviʎʎa osˈsiːa liˈnuːtile prekautˈtsjoːne]) 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). The première of Rossini's opera (under the title Almaviva, o sia L'inutile precauzione) took place on 20 February 1816 at the Teatro Argentina, Rome.

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". Even after two hundred years, it remains a popular work.

Rossini's opera recounts the events of the first of the three plays by French playwright Pierre Beaumarchais that revolve around the clever and enterprising character named Figaro, the barber of the title. Mozart's opera The Marriage of Figaro, composed 30 years earlier in 1786, is based on the second part of the Beaumarchais trilogy. The first Beaumarchais play was originally conceived as an opéra comique, but was rejected as such by the Comédie-Italienne. The play as it is now known was premiered in 1775 by the Comédie-Française at the Théâtre des Tuileries in Paris.
