Athenais Philostorgos I, her surname can be spelt as Philostorgus (Greek: η Άθηναἷς Φιλόστοργος Α', meaning Athenais the loving one, flourished 1st century BC) was a Queen of Cappadocia.
She was the wife of the Cappadocian Persian nobleman and King Ariobarzanes I Philoromaios[1] and through her marriage became a Queen of Cappadocia.
It appears when Ariobarzanes I reigned as King he married Athenais as his Queen.
Athenais bore Ariobarzanes I two children: a son Ariobarzanes II Philopator[1] who later succeeded his father as King and a daughter, Isias Philostorgos who later married the King Antiochus I Theos of Commagene.
Athenais is also known through a surviving honorific inscription dedicated to her son in Athens, Greece dating from the mid 1st century BC.
