Máirtín Ó Direáin ([ˈmˠaːɾʲtʲiːnʲ oː ˈdʲɪɾʲaːnʲ]; 29 November 1910 – 19 March 1988) was an Irish poet from the Aran Islands Gaeltacht. Along with Seán Ó Ríordáin and Máire Mhac an tSaoi, Ó Direáin was, in the words of Louis de Paor, "one of a trinity of poets who revolutionised Irish language poetry in the 1940s and 50s."
