Viola is an unfinished romantic opera by Bedřich Smetana. The libretto was written by Eliška Krásnohorská, and is based on Shakespeare's play Twelfth Night. The composer did some work on it in 1874 and then came back to it in 1883, when he only managed to orchestrate a few scenes; the opera was left incomplete upon Smetana's death in 1884.
