Andrea Casali (17 November 1705 – 7 September 1784) was an Italian painter of the Rococo period. He was called The Chevalier. He was born in Rome and studied under Sebastiano Conca and Francesco Trevisani. Until 1738 he was a decorative painter of Roman churches and in 1729 was made a Knight of the Golden Spur. He travelled to England in 1741 and stayed there for twenty-five years. He was a teacher to James Durno. Some sources erroneously claim a birthdate of 1720 (e.g., Bryan and Hobbes). Among his English patrons were Thomas Coke, earl of Leicester (1697–1759), and Alderman William Beckford. He left England in 1766, after which he lived for some years at Rome, where he died in 1784.
