Aristarchus of Tegea (Ἀρίσταρχος ὁ Τεγεάτης) was a 5th-century BCE tragic poet from Tegea in Arcadia, a contemporary of Sophocles and Euripides who wrote for Athenian dramatic festivals [2]. The Suda lexicon records that he lived to be 100 years old, authored 70 plays, and won two victories, though it also contains the unlikely claim that he taught Sophocles [1].

Only one play title is securely attested: Achilles (Ἀχιλλεύς). The play is lost, but fragments survive, such as a line concerning the "Tegean table" quoted by Athenaeus [1]. It likely treated episodes from the myth of Achilles.

Aristarchus exemplifies the geographical spread of tragic composition beyond Athens in the Classical period. His reported longevity and productivity mark him as a notable figure, and his fragmentary work is of primary interest to scholars studying non-Athenian tragedians and the remains of lost Greek drama [1].
