Ammonius (Ancient Greek: Ἀμμώνιος) of Alexandria, son of Ammonius, was an ancient Greek grammarian who lived around the 1st century BCE.
He was a pupil of a teacher named "Alexander" (possibly Alexander Polyhistor), and became one of the chief teachers in the grammatical school founded by Aristarchus of Samothrace.
[3] He wrote commentaries on Homer, Pindar, and Aristophanes, none of which are extant.
[4][5] He is quoted several times by the grammarian Didymus Chalcenterus, who was another follower of the school of Aristarchus.
