Aristarchus of Thessalonica was an early Christian from Macedonia who is recorded in the New Testament as a companion of the apostle Paul. During his travels, he was caught up in a riot in Ephesus and later accompanied Paul on various journeys, including a voyage toward Rome. He is described in biblical writings as both a fellow laborer and a fellow prisoner of Paul. In certain traditions, he is recognized as a bishop and one of the Seventy Apostles.
