Giovanni Battista Franco (before 1510-1561) was an Italian mannerist painter, draughtsman and engraver. Native of Venice, he spent the first part of his career in Rome, but by 1536 had settled in Florence. Back in Rome by 1542, he painted a fresco of the Capture of Saint John the Baptist for the Oratorio di San Giovanni Decollato. In 1545, he was summoned by Duke Guidobaldo II to Urbino, where he painted frescoes in the Duomo (destroyed). The last ten years of his career were spent in Venice, where among his significant works are a "Baptism of Christ" for San Francesco della Vigna and the ceiling decoration of the Fondaco dei Tedeschi and the Biblioteca Marciana.

Among his drawings there are numerous studies of antique subjects taken from Roman
