Victor of Xanten or Saint Victor is a martyr and saint of the Catholic and the Eastern Orthodox Church. His presumed bones are kept in a shrine since the 12th century that today is embedded into the high altar of the Xanten Cathedral. His feast day is October 10.
Tradition states that Victor was a Praefectus cohortis of a Cohort of the Theban Legion. He was closely associated with Ursus of Solothurn, and is said to have been a relative of Saint Verena. He was executed in the 4th century in the amphitheater of Castra Vetera (the site of present-day Xanten) for refusing to sacrifice to the Roman gods.
