Abdagases I (Greek: Ἀβδαγάσης, epigraphically ΑΒΔΑΓΑΣΟΥ; Kharosthi: 𐨀𐨬𐨡𐨒𐨮 A-va-da-ga-ṣa, Avadagaṣa) was an Indo-Parthian king, who ruled Gandhara and possibly over most of the Indus region from c. 46 to 60 AD. He was a nephew and successor of Gondophares, who had laid foundations for the Indo-Parthian kingdom after revolting against his Arsacid overlords in c. 19 AD. Abdagases was succeeded by Orthaghnes or Pacores.
