Raffaello Vanni (1590-1657) was an Italian painter of the Baroque.
He was born at Siena. He first trained with his father, Francesco Vanni, who died in 1610. He was afterwards sent to Rome, and recommended to the care of Antonio Carracci. He became a follower of the style of Pietro da Cortona. He painted a Birth of the Virgin for Santa Maria della Pace. He also painted for Santa Maria del Popolo. A Marriage of S. Catharine by him is in the Pitti Palace, and other pictures at Siena and Pisa. He was a member of the Accademia di San Luca in 1655. His brother, Michelangelo Vanni, is better known as the inventor of a process of making pictures by staining marble than as an artist. One of Raffaello's pupils was Deifebo Burbarini.
