Máirtín Ó Direáin (['m?a???t?i?n? o? 'd????a?n?]; 29 November 1910 – 19 March 1988) was an Irish poet who is widely held to be one of the foremost Irish language poets of the twentieth century.
A native of the Aran Islands Gaeltacht, Ó Direáin later spent time working in Galway and Dublin, where he upheld a connection to Gaelic affairs through Conradh na Gaeilge and Taibhdhearc na Gaillimhe.
A significant theme of his poetic works deals with the tensions between the urban and rural, modernity and tradition, the English-speaking world and Gaeldom.
