(Ἀλέξαρχος), a Greek historian, who wrote a work on the history of Italy (Ἰταλικά), of which Plutarch (Parallel. 7) quotes the third book. Servius (Serv. ad Aen. 3.334) mentions an opinion of his respecting the origin of the names Epeirus and Campania, which unquestionably belonged to his work on Italy. The writer of this name, whom Plutarch mentions in another passage (De, Is. et Os. p. 365), is probably a different person.
