Alcimus Ecdicius Avitus was a Latin poet and bishop of Vienne in Gaul. His fame rests in part on his poetry, but also on the role he played as secretary for the Burgundian kings.

The Archbishopric of Vienne, named after its episcopal seat in Vienne in the Isère département of southern France, was a metropolitan Roman Catholic archdiocese. It is now part of the Archdiocese of Lyon.
