Apollodorus of Carystus was a Greek comic poet of the New Comedy period, active in the early to mid-3rd century BCE. A native of Carystus in Euboea, he was a contemporary and competitor of Menander, winning five victories at Athenian dramatic festivals. Ancient sources note he was the son of Scymnus, but few other personal details survive.

Though only fragments and titles remain, Apollodorus was a prolific playwright. His comedies are known primarily through later Roman adaptations. Significant works include Hecyra and Phormio, both adapted by Terence. Other attested titles are Epidikazomenos, Apokarteron, Hieres, Paidion, and Sphattomene.

Apollodorus is a key figure of later New Comedy, bridging the Athenian tradition and Roman adaptation. His primary importance lies in providing source material for Roman dramatists; Terence’s adaptations of Hecyra and Phormio offer crucial evidence for his style and the process of contaminatio. His works exemplify standard New Comedy themes of family conflict and romantic intrigue, which entered the Western literary canon through these Latin versions.
