Pope Sabinian (Latin: Sabinianus) was Pope from 13 September 604 to his death in 606, during the Byzantine (Eastern Roman) domination of the Papacy. He was the fourth former apocrisiarius to Constantinople to be elected pope.
Sabinian was born at Blera (Bieda) near Viterbo. He had been sent by Pope Gregory I as Apostolic nuncio, to Constantinople, but he apparently was not entirely satisfactory in that office. He returned to Rome in 597. He was probably consecrated pope on 13 September 604.
