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.

[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.

[4] His bones were temporarily removed in 2006 whilst the chapel underwent restoration, but they have since been returned.

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