Benignus of Armagh was a 5th-century Irish priest and archbishop who served as a close associate of Saint Patrick. Born to a chieftain named Sesenen in the region of modern-day County Meath, he received baptism from Patrick himself. He held the position of coadjutor within the Armagh diocese and acted as a musical psalm-singer for the saint. Throughout his career, he served as the secretary to the Commission of Nine and became the inaugural rector of the school at Armagh.
