Giuseppe Pierre Joseph Grisoni (bapt. October 24, 1699–1769), also known as Grifoni or Grison, was an Italian painter and sculptor, noted for his landscapes and historical tableaux.
Born in Mons, he studied in Florence under Tommaso Redi, abandoning his Flemish influences for the Italian tradition. In 1715 he travelled to London with John Talman and tried to establish himself as a portrait painter. He did not achieve enough success to stay, however, and returned to Florence in 1728 to teach at the Academy of Fine Arts. In 1740, he briefly relocated to Pisa before settling in Rome where he died.
