Titus Flavius T. f. Sabinus was the father of the emperor Vespasian.
Sabinus was the son of Titus Flavius Petro and his wife, Tertulla, and was an eques from Reate in the Sabine region of Italy. He served as a customs official and then as a banker in the province of Asia, where he was honoured with statues dedicated "To an Honest Tax-gatherer", and later as a banker at Aventicum among the Helvetii in Gaul, where he died.
With his wife, Vespasia Polla, he had at least two sons, the consul Titus Flavius Sabinus, and Titus Flavius Vespasianus, the future emperor Vespasian; and also a daughter who died in infancy, Flavia Vespasia. He may have had an elder son, who was the father of Titus Flavius Sabinus, consul in AD 69.
