John McKenna (January 6, 1880 – November 26, 1947) was an Irish-American musician originally from Tents, Tarmon, County Leitrim, midway between Drumkeeran and Drumshanbo.
He married local nurse Mary Jane Keaveney on 13 September 1909 in Brigid's Church, Drumkeeran.
John McKenna was responsible for reintroducing Leitrim tunes such as "Lucky in Love", "The Sailor and the Rock" and the "Happy Days of Youth".
His legacy of recordings made him one of the most influential flute players in Irish traditional music – he has influenced De Dannan, Frankie Gavin and Matt Molloy.
Shortly afterwards the John McKenna Music Festival was instituted, which takes place every year in Drumkeeran.
