The Exarchate of Ravenna was an ad hoc organisation of the Byzantine dominions in Italy, established c.584, in the face of the Lombard invasion and gradual conquest of much of the Italian peninsula.

The list of the exarchs of Byzantine Ravenna is very uncertain, as the sources are scarce, and not without contradictions. Also note that some served two separate periods.

Praetorian prefects of Italy

Before the creation of the Exarchate of Ravenna as the formal organisation of Byzantine Italy, the province was governed by Pretorian Prefects, of which the last were:

• Narses (553–568) under Justinian.
• Longinus (568–?) under Justine II.

The last testimony we have of Longinus is from 575, but nothing is known of the length of his tenure, or when he died.
