John of Gaza the Grammarian and Poet was a grammarian and poet active in Gaza during the late 5th and early 6th centuries CE. His epithet indicates his profession as a teacher of language and literature within the city’s vibrant late antique cultural milieu, where classical education was adapted within a Christian framework.

He is distinct from other contemporary figures from Gaza as the author of the Description of the Cosmic Table. His two known works are the Description of the Cosmic Table, an extant ekphrastic hexameter poem describing a cosmological painting in a bathhouse, and a collection of Anacreontic Poems, of which only six short verses survive.

John is significant as an example of a late antique grammarian-poet who employed classical literary forms for contemporary purposes. His Description of the Cosmic Table is a key source for the study of ekphrasis, late antique aesthetics, and the reception of classical cosmology, illustrating the persistence of Hellenic literary culture in a Christian setting.
