Agostino di Duccio (1418 – c.1481) was an early Renaissance Italian sculptor.

Born in Florence, he worked in Prato with Donatello and Michelozzo, who influenced him greatly. In 1441, he was accused of stealing precious materials from a Florentine monastery and was banished from his native city as a result. The following year he continued the work on the altar of S. Geminiano for the Cathedral of Modena, a work noticeable for the influence of Michelozzo.
