Apollonius οf Athens (Ancient Greek: Άπολλώνιος ό Άθηναίος), also known as Apollonius of Naucratis, was a Greek sophist and rhetorician who lived in the time of the Roman emperor Septimius Severus, at the end of the 2nd century.
He was an opponent of Heracleides, and with the assistance of his associates he succeeded in expelling him from the chair of rhetoric in Athens.
He held several high offices in his native place, and distinguished himself no less as a statesman and diplomatist than as a rhetorician.
Apollonius cultivated chiefly political oratory, and used to spend a great deal of time upon preparing his speeches in retirement.
His declamations are said to have excelled those of many of his predecessors in dignity, beauty, and propriety; but he was often vehement and rhythmical.
