Willie Clancy (24 December 1918 – 24 January 1973) was an Irish uilleann piper.

Clancy was born into a musical family at Islandbawn near Milltown Malbay, County Clare. His parents (Gilbert Clancy and Ellen Killeen) both sang and played concertina, and his father also played the flute. Clancy's father had been heavily influenced by local blind piper Garret Barry and passed much of Barry's music on to Willie.
