Guillaume Tell (, ) is an opera in four acts by Gioachino Rossini to a French libretto by Étienne de Jouy and Hippolyte Bis. Based on Friedrich Schiller's play William Tell, which drew on the William Tell legend, the opera was Rossini's last, although he lived for nearly forty more years. The overture, in four sections and featuring a depiction of a storm as well as a vivacious finale, the "March of the Swiss Soldiers," is often played.
