Pope Eutychian, also called Eutychianus, was the Bishop of Rome from 4 January 275 to his death in 283.
His original epitaph was discovered in the catacomb of Callixtus, but almost nothing more is known of him. Even the date of his reign is uncertain. Liber Pontificalis gives a reign of 8 years and 11 months, from 275 to 283. Eusebius, on the other hand says his reign was only 10 months.
