Gordianus (died 362) was a Roman martyr who was killed during the reign of Julian the Apostate, and is commemorated on 10 May.

He was charged with forcing Januarius to make a sacrifice to the Emperor, but instead was persuaded and then converted to Christianity with many within his household.

[2] Being accused before his successor, or as some say before the prefect of the city, Apronianus, he was tortured and finally beheaded.

[1] Some time later the remains of Gordianus were moved to the Cyriaca cemetery and there they lay until the 1670s, when a monk named Ambrose of the Order of St Augustin removed them and gave them to Christopher Anderson, a Jesuit priest.

The Princely Abbey of Kempten in Bavaria was established in 752, and dedicated to the Virgin Mary and Gordianus and Epimachus.
