Mícheál Ó Muircheartaigh (1930-) is a broadcaster. Born in Dún Síon, near Dingle, Co. Kerry, his first broadcast was on a Railway Cup match in 1949 after being selected for the job following a test commentary on a hurling game.
He has since become the public voice of the GAA with his uniquely entertaining and often bilingual commentaries.
Ó Muircheartaigh worked as a teacher before becoming a full-time broadcaster with RTÉ during the 1980s. He retired from broadcasting in October 2010.
