La straniera is an opera in two acts with music by Vincenzo Bellini to an Italian libretto by Felice Romani, based on the novel L'Étrangère by Charles-Victor Prévot, vicomte d'Arlincourt, although writer Herbert Weinstock also adds that it is "more likely [based on] a dramatization of [that novel] in Italian by Giovan Carlo, barone di Cosenza" since he then quotes a letter from Bellini to his friend Francesco Florimo in which he says that Romani "certainly will not follow the play" [suggesting then that they were aware of its existence.]

Vincenzo Salvatore Carmelo Francesco Bellini was an Italian opera composer, who was known for his long-flowing melodic lines for which he was named "the Swan of Catania". Many years later, in 1898, Giuseppe Verdi "praised the broad curves of Bellini's melody: 'there are extremely long melodies as no-one else had ever made before'."
