Giambettino Cignaroli (July 4, 1718 – December 1, 1770) was an Italian painter of the Rococo and early Neoclassic period.
He was born and died in Verona. He was a pupil of Santo Prunato and Antonio Balestra and active mostly in the area of the Veneto. He became the director of the academy of painting and sculpture of Verona in December 1764.
For the Austrian governor of Lombardy and a collector of antiquities, Count Karl von Firmian, Cignaroli painted two canvases on Greco-Roman episodes, a thematic preferred by Neoclassic painters: Death of Cato (1759) and Death of Socrates.
