Boeus was a Greek poet who lived during the Hellenistic period, around the 3rd century BCE. He is known only as an author of epic poetry, writing in the traditional Homeric style of hexameter verse. No details about his personal life or origin have survived.

His sole known work is a poem titled Ornithogonia, or "The Generation of Birds." The poem itself is lost, and our knowledge of it comes from fragments and references in later ancient writers. According to these sources, the poem described the origins and metamorphoses of various birds, often explaining how they were transformed from humans or mythological figures.

Boeus's significance lies in his contribution to a specialized type of Hellenistic literature. Modern scholars see his work as an early example of a cataloguing tradition that used poetry to systematize mythological explanations for the natural world. His poem represents a niche but documented strand of literary activity focused on origin stories. It was used as a source by later mythographers, indicating it was considered an authoritative reference on avian mythology in the ancient world.
