Bertoldo di Giovanni (after 1420 Poggio a Caiano – 28 December 1491 Florence) was an Italian sculptor and medallist.

He was a pupil of Donatello and for a long time worked in his master's workshop, carrying out his unfinished works after his death in 1466, for example the bronze pulpit reliefs from the life of Christ in the Basilica di San Lorenzo di Firenze in Florence. He later became head and teacher of the school for painters and in particular for sculptors, which Lorenzo de' Medici had founded in his garden. At the same time, Bertoldo was the custodian of the antiques there. Some of the most significant sculptors of their time attended this school, such as Michelangelo, Baccio da Montelupo, Giovanni Francesco Rustici and Jacopo Sansovino.
Bertoldo di Giovanni is the sculptor of a medal of Sultan Mohammed II (see image). He is the author of several medals that were formerly attributed by error to Antonio Pallaiuolo.
