Tadhg Mac Dhonnagáin

Tadhg Mac Dhonnagáin is an Irish language television personality from Aghamore, County Mayo in Ireland. Originally a schoolteacher, Mac Dhonnagáin was invited to present children's programmes on RTÉ Television in the early 1980s. He went on to become an anchoring presenter on the Irish language arts programme, Cúrsaí Ealaíona.

Mac Dhonnagáin, a guitarist and singer, also recorded two albums while working for RTÉ in Dublin: Solas Gorm, a tongue-in-cheek blues collection, and Raiftearaí san Underground, a more-serious collection in Irish and English.

With the creation of TG4 in 1996 and the concomitant rise of an Irish language television industry in the West of Ireland, Mac Dhonnagáin resettled in the Conamara Gaeltacht, where he is a scriptwriter for television dramas and comedies, most notably the Irish Film and Television Awards winning teenage drama show Aifric, and the owner/director of a music publisher, Futa Fata, which specializes in material for children. The publisher's most successful production to dateFact|date=May 2008 has been the award-winning Gugalaí Gug, a collection of children's rhymes put to music.

Mac Dhonnagáin lives in Conamara with his wife and four children.

In 2007 Mac Dhonnagáin was named Uachtarán an Oireachtais, an honorary title given by the Irish language festival Oireachtas na Gaeilge, which was being held in Westport that year.
