Eoghan Rua Ó Súilleabháin (1748 – 29 June 1784), anglicized as Owen Roe O'Sullivan ("Red Owen"), was an Irish poet. He is known as one of the last great Gaelic poets. A recent anthology of Irish-language poetry speaks of his "extremely musical" poems full of "astonishing technical virtuosity", and also notes that "Eoghan Rua is still spoken of and quoted in Irish-speaking districts in Munster as one of the great wits and playboys of the past."
