Auspice d'Apt was an early Christian prelate who served as the first bishop of Apt in France. According to hagiographic tradition, he received his consecration from Pope Clement I. During the reign of the Roman Emperor Trajan, he was martyred for his faith. His name is preserved in ancient religious texts, including the Acts of Saint Auspice and the passion of the martyrs Nereus and Achilles, whom he reportedly buried.
