Ascanio in Alba, K. 111, is a pastoral opera in two parts (Festa teatrale in due parti) by Wolfgang Amadeus Mozart to an Italian libretto by Giuseppe Parini.

It was performed in October 2006 on the 250th anniversary of Mozart's birth at La Scala, Milan, under the baton of Giovanni Antonini.

Aceste tells the shepherds that their valley will be the site of a fine city and that they will have a sovereign, Ascanio, before the day is out.

Venus then appears to Ascanio and asks him to test the girl a little longer before revealing his true identity.

Silvia and Ascanio add their voices to the chorus and the goddess descends on her chariot surrounded by clouds.
