Séamus Ennis (1919 – 1982) was an Irish musician, singer and Irish music collector. He was most noted for his uilleann pipe playing and was partly responsible for the revival of the instrument during the twentieth century, having co-founded Na Píobairí Uilleann, a nonprofit organization dedicated to the promotion of the uilleann pipes and its music. He is recognised for having preserved almost 2,000 Irish songs and dance-tunes as part of the work he did with the Irish Folklore Commission. Ennis is widely regarded as one of the greatest uilleann pipers of all time.
