Saint Gratus of Aosta (Italian: San Grato di Aosta) (d. September 7 c. 470 AD) is the patron saint of Aosta. He is known to have signed the acts of the synod of Milan in 451 AD as a priest. Gratus represented the bishop of Aosta Eustasius at this council signing the letter that the assembly sent to Pope Leo I the Great in order to affirm its condemnation of the heresy of Eutyches.
