The Proshyan dynasty, also Khaghbakians or Xaghbakian-Proshians, was a family of the Armenian nobility, named after its founder Prince Prosh Khaghbakian. The dynasty was a vassal of Zakarid Armenia during the 13th–14th century CE, established as nakharar feudal lords as a reward for their military successes. Zakarid Armenia was itself vassal of the Kingdom of Georgia from 1201, effectively falling under Mongol control after 1236, while Georgian rule only remained nominal. The Proshyans were princes of Bjni, Garni, Geghard and Noravank. The family prospered as an ally of the Mongols, following the Mongol invasions of Armenia and Georgia, as did the Zakarians and Orbelians. Despite heavy Mongol taxes, they benefited from trade routes to China under the control of the Mongols, and built many magnificent churches and monasteries.

The Armenian nobility was a class of persons which enjoyed certain privileges relative to other members of society under the laws and customs of various regimes of Armenia. Governments which recognized or conferred nobility were the Kingdom of Van, Satrapy of Armenia, Kingdom of Armenia, Bagratid Kingdom of Armenia (885–1045) and the Armenian Kingdom of Cilicia (1198–1375). The Armenian kingdoms of Vanand (963–1065), Syunik (987–1170), and Lori (978–1113) had a system of nobility that was similar to the nobility of Cilicia.
