The Canons Regular of St. Augustine are priests who live in community under a rule and are generally organised into religious orders, differing from both secular canons and other forms of religious life, such as clerics regular, designated by a partly similar terminology. As religious communities, they have laybrothers as part of the community.

Augustine of Hippo, also known as Saint Augustine, was a theologian and philosopher of Berber origin and the bishop of Hippo Regius in Numidia, Roman North Africa. His writings influenced the development of Western philosophy and Western Christianity, and he is viewed as one of the most important Church Fathers of the Latin Church in the Patristic Period. His many important works include The City of God, On Christian Doctrine, and Confessions.
