Confessions (Latin: Confessiones) is the name of an autobiographical work, consisting of 13 books, by St. Augustine of Hippo, written in Latin between AD 397 and 400. Its original title was Confessions in Thirteen Books, and it was composed to be read out loud with each book being a complete unit.

The work outlines St. Augustine's sinful youth and his conversion to Christianity. It is widely seen as the first Western autobiography ever written, and was an influential model for Christian writers throughout the following 1,000 years, through the Middle Ages. It is generally considered one of Augustine's most important texts.
