Aogán Ó Rathaille (1675? – 1729) was an Irish language poet. He was the first and greatest exponent of the aisling genre.

Ó Rathaille was born in County Kerry into a relatively prosperous family. He was educated in Latin and English as well as Irish literature and history. His best-known poem is the great aisling Gile na Gile (Brightness Most Bright). His work reflects the chaotic nature of native Irish society and culture in the wake of the defeat of the Roman Catholic cause at the Battle of the Boyne in 1690.
