Severus of Vienne (died c. 455) was a priest who evangelised in Vienne, France. He is venerated as a saint in the Catholic Church as well as in other denominations. Severus was reportedly Indian by birth and of wealthy origins. His entry in the Roman Martyrology reads:
Severus settled in Vienne around 430. He founded a church in honour of Saint Alban (now the church of Saint-Alban-du-Rhône) near Vienne. He died in Italy, but his body was brought back to Vienne and buried in the church dedicated to the protomartyr Saint Stephen, which he himself had constructed.
