Dosiadas of Crete was a Hellenistic poet of the 3rd century BCE. His geographical epithet confirms his origin from the island of Crete. No further biographical details about his life or education survive.

Two pattern poems are attributed to Dosiadas. His primary surviving work is the "Altar", a shaped poem preserved in the Greek Anthology. A second poem, the "Axe", is also attributed to him by the Byzantine scholar Michael Psellus, though its authenticity is less certain. Both works are fragmentary examples of visual poetry.

Dosiadas is a significant practitioner of Hellenistic pattern poetry, where the visual arrangement of words forms a shape related to the subject. His "Altar" is a key example, with lines arranged to form an altar's shape and composed in the Doric dialect. This work places him within a circle of innovative poets, including Simias of Rhodes and Theocritus, and his poetry is studied for its formal and linguistic characteristics as an artifact of Hellenistic literary experimentation.
