Breandán Breathnach (1 April 1912 – 6 November 1985) was an Irish music collector and uilleann piper.
His uncle Joe was a player of the uilleann pipes and a member of the Piper's Club.
He started learning the pipes from John Potts of Wexford and William Andrews, then with the renowned piper Leo Rowsome.
The collection was called Ceol Rince na hÉireann ("Dance Music of Ireland").
His efforts were responsible for saving numerous tunes and he is generally recognised as a major figure in the preservation and continuation of traditional Irish music.
