L’incontro improvviso (The unexpected encounter) (Hob. XXVIII:6) is an opera in three acts by Joseph Haydn first performed at Eszterháza on 29 August 1775 to mark the four-day visit of Archduke Ferdinand, Habsburg governor of Milan and his consort Maria Beatrice d'Este. The opera is designated a dramma giocoso (a comic opera) and is an example of the then Austrian fascination with Turkish subjects.
