Diarmuid Ó Gráinne (10 May 1950 – 28 August 2013) was an Irish-language writer and journalist from the County GalwayGaeltacht. He wrote for the newspaper, Lá and featured on Raidió na Gaeltachta. He released a number of books, perhaps best known works are his semi-autobiographical novel writings An Traimp and Muintir na Coille.
Ó Gráinne was strongly influenced by his fellow Connemara-man, Máirtín Ó Cadhain whose death he felt left a hole in the leadership of the Irish-language movement. Ó Gráinne also became interested in some Continental European authors, translating writings by or autobiographies about Karl Marx, Albert Camus and Friedrich Nietzsche into Irish.
