Sabinus of Piacenza was a 4th-century prelate who served as the bishop of Piacenza for approximately fifty years. Born in Milan, he initially held the position of deacon in his home city before ascending to the episcopacy. During his career, he played a significant role in the Council of Antioch in 372, where he worked to protect Catholic doctrine from the Arian heresy. He remained the leader of the Piacenza see until his death in 420.
