Florentine painter of the early Italian Renaissance who was a pupil of Giotto (Giotto di Bondone) and was influenced by Pietro Lorenzetti (Lorenzetti, Pietro). Daddi's efforts to fuse the plastic qualities of Giotto's art with some aspects of Sienese art came to represent the dominant style of painting directly after Giotto. Daddi's work, from the period 1328–48, ranges from Madonna images in large church altarpieces to small panels for citizens' prayers. Though known for his technique of building up his figures with the softened weight expected of a Giotto pupil, Daddi added grace by emphasizing a curving line. His figures have a sharp, bright presence as they turn before tapestried thrones.

A triptych Daddi completed in 1328 for the Church of Ognissanti (now in the Uffizi, Florence) is typical of his best work. Numerous panel paintings by the artist are to be found in museums in Europe and North America.
