Antonio del Castillo y Saavedra was a Spanish Baroque painter, sculptor, and poet.

Antonio del Castillo y Saavedra was born at Córdoba, Spain.

He trained in painting under his father Agustín del Castillo, and after his death by a little-known religious painter named Ignacio Aedo Calderón from 1631 to 1634. Later he was taught in Seville by Francisco de Zurbarán and by his uncle Juan del Castillo, who was also teacher of Cano, Murillo and De Moya. In 1635 he returned to Córdoba, where he painted frescoes and oil paintings (such as those in the church of Santa Marina).

He died at Córdoba in 1668.
