Maometto II (or Maometto secondo) is an 1820 opera in two acts by Gioachino Rossini to an Italian libretto by Cesare della Valle. Set in the 1470s during a time of war between the Turks and Venetians, the work was commissioned by the Teatro di San Carlo in Naples. Della Valle based his libretto on his earlier play Anna Erizo. The name of the title character, Maometto II, refers to the real-life Ottoman Sultan and conqueror of Constantinople Mehmed II, who lived from 1432 to 1481.
