Macedoniarch (Greek: μακεδονιάρχης) was a Roman-era title for the president of the Koinon of Macedonians.
[2][3] The office was also considered an important official of the Synhedrion, a provincial council consisted of municipal aristocracy, Roman citizens, and - in some cases - slaves and freedmen.
[4] The Macedoniarch also headed an influential club called the society of Sarapiasts starting from the reign of the Severan dynasty.
[6] The title was only held by 11 people, six of which are believed to be of Roman descent, based upon them having a cognomen.
