Giovanni Andrea Donducci (1575–1655), also known as Mastelletta, was an Italian Baroque painter of the Bolognese School (painting).
Born in Bologna, he trained in the Carracci Academy degli Incamminati at about the time when Domenichino, Lucio Massari, and perhaps Albani were there.
He belongs to the generation of Carracci- inspired or trained painters comprised by Giacomo Cavedone (1577–1660); Alessandro Tiarini (1577–1668), Lucio Massari, Lionello Spada (1576=1622), and Lorenzo Garbieri.
Art biographer Malvasia claims he befriended the Genoese Agostino Tassi while in Rome.
Malvasia describes him by the late 1620s as increasingly neurotic and reclusive: “an enemy of his friends, suspicious of everyone, hating himself, in other words".
