Alexander of Lyon was a Christian martyr from Phrygia who lived during the second century. He was a close childhood companion of Epipodius, a physician, and both men were executed in Lugdunum during the reign of Marcus Aurelius. After being betrayed to imperial authorities by a servant, the two friends openly declared their Christian faith. Following the brutal execution of his companion, Alexander expressed a desire to share the same fate, leading to his own martyrdom.
