Agostino Ciampelli was an Italian painter of the Baroque period. He trained with Santi di Tito in Florence, and painted in Rome under Clement VIII, including a Crucifixion for Santa Prassede and a Saint Giovanni Gualberto in its sacristy; Angels on the walls above the choirstalls in the apse of Santa Maria in Trastevere; frescoes of the Stoning of Saint Vitale in San Vitale and further frescoes in the little church of Santa Bibiena; and The Visitation in Sant Stefano di Pescia. At the Basilica of San Giovanni in Laterano, Ciampelli frescoed the walls of the canons' sacristy, the "Sala Clementina".
