Giovanni Stefano Robatto (1649–1733) was an Italian painter of the Baroque period. He was born at Savona. He studied at Rome under Carlo Maratti. He was employed painting for churches in Genoa, among his works, a St. Francis receiving the Stigmata for the church of the Cappucini. He afterwards abandoned himself to a fatal passion for gaming, and his later works are hasty and careless.
