The Augustine of Hippo bibliography contains a list of works published by fourth-century Christian bishop and theologian Augustine of Hippo. Augustine was one of the most prolific Latin authors in terms of surviving works, and the list of his works consists of more than one hundred separate titles. They include apologetic works against the heresies of the Arians, Donatists, Manichaeans and Pelagians; texts on Christian doctrine, notably De Doctrina Christiana (On Christian Doctrine); and exegetical works such as commentaries on Book of Genesis, the Psalms and Paul's Letter to the Romans; along with many sermons and letters.
