Trophimus of Arles was a third-century bishop who is traditionally recognized as the first bishop of Arles in modern-day France. According to Catholic tradition, he was one of seven bishops sent from Rome to Gaul by Pope Fabian during the reign of the co-emperors Decius and Herennius Etruscus. While some later traditions incorrectly identified him as a companion of the Apostle Paul, historical accounts place his arrival in Gaul during the middle of the third century.
