Arctinus of Miletus or Arctinus Milesius (Ancient Greek: Ἀρκτῖνος Μιλήσιος) was a Greek epic poet whose reputation is purely legendary, as none of his works survive. Traditionally dated between 775 BC and 741 BC, he was said to have been a pupil of Homer. His father was Teleus son of Nauteus.Phaenias of Eresus placed him in the 7th century BC and claimed that he was defeated by Lesches of Pyrrha in competition. One of the "cyclic poets", Arctinus composed the epics Aethiopis and Sack of Troy, which were contributions to the Trojan War cycle, and possibly Naupactia.
These poems are lost, but an idea of the first two can be obtained from the Chrestomathy ascribed (probably wrongly) to Proclus the Neo-Platonist of the 5th century AD.
