Carlo Innocenzo Carlone or Carloni was an Italian painter and engraver, active especially in Germany.
He was a native of Scaria, near Como, in Lombardy, but may have been from the Carloni family of Genoese painters. He was the son of a sculptor, but he preferred painting, and was placed under the care of Giulio Quaglio. He subsequently trained also with Giovanni Battista Colomba. He afterwards studied at Venice and at Rome, with Francesco Trevisani until he was 23 years of age, when he visited Germany, where he has left works in oil and in fresco at Ludwigsburg, Passau, Linz, Breslau, Prague, and Vienna.
He painted large decorative fresco cycles for palaces in Vienna, Prague and Southern Germany. For example, Carlone is known for painting the ceiling images in the Upper Belvedere of the Belvedere palace complex. His The Glorification of Saints Felix and Adauctus (1759–1761) was commissioned for the cupola of the church of San Felice del Benaco on Lake Garda. He died at Como.
