Moschion is an obscure tragic poet placed in the 2nd century CE. No biographical details concerning his life, origins, or associations are recorded.

His only known work is the tragedy Telephus, preserved in fragments. A substantial fragment, transmitted by the anthologist Stobaeus, contains a speech arguing against the practice of human sacrifice.

Moschion’s importance derives solely from this single fragment. The speech is a rhetorical set-piece against those who sacrifice human beings. It employs philosophical reasoning to condemn the custom as barbaric, reflecting contemporary ethical discourse. The fragment is a valuable, if isolated, example of later Imperial tragic composition, valued in antiquity primarily for its moral content.
