Apollonides was a tragic poet of the 3rd century BCE during the Hellenistic period. The sole source for his biography is the 10th-century Byzantine encyclopedia, the Suda, which identifies him as a contemporary of Ptolemy II Philadelphus and the poet Sositheus. This places him within the Alexandrian literary milieu centered on the Library and Museum, where tragedy was cultivated in a courtly and scholarly context.

The Suda attributes a single tragedy to Apollonides: The Suppliants, noted as a "new" play, indicating an original composition. The work is lost, and no fragments survive.

Apollonides is a documented, though minor, figure in the continuation of tragic poetry into the Hellenistic age. His recorded association with Ptolemaic Alexandria and with a known poet like Sositheus helps map the network of court-supported artists in the period. With no surviving text, his literary impact remains unknown, but his attestation contributes to the historical record of post-Classical drama.
