The Diocese of Pontus (Latin: Dioecesis Pontica, Greek: Διοίκησις Πόντου/Ποντικής) was a diocese of the later Roman Empire, incorporating the provinces of northern and northeastern Asia Minor up to the border with the Sassanid Empire. The diocese was established after the reforms of Diocletian, was subordinate to the Praetorian prefecture of the East, and was abolished during the reforms of Justinian I in 535.

It included 12 provinces: Bithynia, Honorias, Paphlagonia, Helenopontus, Pontus Polemoniacus, Galatia I and Galatia II (Salutaris), Cappadocia I and Cappadocia II, Armenia I, Armenia II, Armenia Maior and the autonomous Armenian principalities (Satrapiae) in the area of Sophene.
