Taddeo Gaddi (c.1300-1366) was an Italian painter, active during the early Renaissance.

He was an assistant to the painter Giotto and the father of the painters Giovanni Gaddi , Agnolo Gaddi and Niccolò Gaddi ; his fourth son, Zanobi, does not appear to have been an artist.

His work includes frescoes in the Baroncelli Chapel at Santa Croce in Florence (1328-38) as well as:
