Giovanni di Balduccio (c. 1290 – after 1339) was an Italian sculptor of the Medieval period. He was born in Pisa, and likely did not train directly with the famous Pisan sculptor Andrea Pisano. He travelled to Milan to help sculpt the arc of St. Peter Martyr now in the Portinari Chapel, in the Basilica of Sant'Eustorgio, work signed in 1339. He also worked on the portal of the church of the Brera in Milan. He also worked in San Casciano in Val di Pesa and in the monument of Guarniero in Sarzana.
