Lo straniero (The Stranger) is an opera (dramma lirico) in two acts composed by Ildebrando Pizzetti, who also wrote the libretto.

An original story with characters from the Old Testament, it is the third work in Pizzetti's trilogy on the themes of redemption and the virtue of love.

Although it did not receive its premiere until 1930, Pizzetti had begun the project several years earlier.

[1] Lo straniero premiered on 29 April, 1930, at the Teatro dell'Opera di Roma.
