The Vita Germani is a hagiographic text written by Constantius of Lyon in the 5th century AD. It is one of the first hagiographic texts written in Western Europe, and is an important resource for historians studying the origins of saintly veneration and the "cult of saints." It recounts the life and acts of bishop Germanus of Auxerre, who travelled to Britain c. 429 AD, and is the principal source of details about his life. It is one of the few surviving texts from the 5th century with information about Britain and the Pelagian controversy, and is also one of the first texts to identify and promote the cult of Saint Alban.
