Marcus Gnaeus Licinius Rufinus (Ancient Greek: Μ. Γναῖος Λικίνιος Ῥουφεῖνος fl. ca. 210–240)[1] was a Roman Imperial official, senator and jurist from Thyateira in Lydia. He held a number of secretarial posts for the emperor, served as governor of Noricum, and was one of the twenty senators who led the resistance against Maximinus Thrax's invasion of Italy in 238 AD. He is known from extracts of his legal work, Regulae and from honorific inscriptions erected for him in Thyateira, Thessaloniki, and Beroea.
