(Gaius) Vettius Gratus[1] (fl. 3rd century) was a Roman senator who was appointed consul in AD 250.
A member of the Patrician gens Vetti,[2] Vettius Gratus was related to the consuls Gaius Vettius Gratus Atticus Sabinianus (possibly his brother or cousin) and Gaius Vettius Gratus Sabinianus (possibly his grandson or grand-nephew).
In AD 250, Vettius Gratus was appointed consul posterior, serving alongside the emperor Decius.[3]
It is speculated that Vettius Gratus had a son, Gratus, who became consul in AD 280.[4]
