Giovanni Alberto Ristori (1692 - 7 February 1753) was an Italian opera composer and conductor. He is thought to have been born in Bologna, and was the son of Tommaso Ristori, the leader of an opera troupe belonging to the King of Poland and Elector of Saxony August II the Strong (based in Dresden). August II 'loaned' his opera troupe to the Russian Empress Anna for the celebration of her coronation in Moscow. Ristori died in Dresden.
