Athenais Philostorgos I

Athenais Philostorgos I, her surname can be spelt as Philostorgus (, meaning Athenais the loving one, flourished 1st century BC) was a Queen of Cappadocia.

Athenais was a Greek noblewoman of obscure origins. She was the wife of the Cappadocian Persian nobleman and King Ariobarzanes I Philoromaios and through her marriage became a Queen of Cappadocia. Ariobarzanes I reigned as King of Cappadocia from 95 to 63/62 BC.

It appears when Ariobarzanes I reigned as King he married Athenais as his Queen. Little is known on how she reigned as Queen and her relationship with her family. Athenais bore Ariobarzanes I two children: a son Ariobarzanes II Philopator 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.
