He was born into a family of poets and storytellers, which included his brothers Séamus Ó Grianna and Seán Bán Mac Grianna, in Ranafast, County Donegal, at a time of linguistic and cultural change.
He was educated at Saint Eunan"s College, Letterkenny, and Street Columb"s College in Derry. He trained as a teacher in Street Patrick"s College, Dublin, from which he graduated in 1921.
He became involved in the Irish war of independence, and in the civil war was interned as a republican by the pro-treaty government for fifteen months. He began a teaching career but, with his poetic and independent character, soon discovered that his vocation did not lie there. Mac Grianna started writing in the early 1920s, and his creative period lasted some fifteen years.
He wrote essays, short stories, travel and historical works, a famous autobiography, Mo Bhealach Féin, and a novel, as well as translating many books
He was imbued with a strong, oral traditional culture from his childhood, and this permeated his writings, particularly in the early years. Towards the end of his career, Mac Grianna grew increasingly analytical and critical as he examined the changing face of the Irish-speaking districts and the emergence of an Anglicised Ireland with no loyalty to, or sympathy with, a heroic and cultured past
He was probably the greatest Gaeltacht writer of his time, whose work had developed considerably before he was stricken by a severe depressive psychosis in 1935. That same year he admitted himself to Street.Conall"s psychiatric hospital in Letterkenny, where he stayed for most of the next 31 years.
He died in 1990.
