Fulgentius of Cartagena was a 6th-century bishop who served the church in the Visigothic Kingdom of Hispania. Born in Cartagena, he was part of a religious family that included his brothers, the Archbishops Leander and Isidore of Seville. He eventually held the see of Astigi (modern Écija), likely following the influence of his brother Leander. Throughout his career, he participated in significant ecclesiastical matters, including the establishment of the province of Toledo and the Second Synod of Seville.
