Catrióna Fee is a concertina player from Cold Spring, New York who is currently based in Washington, D.C. She is a triplet, the sister of Mairead Fee and Angela Fee, who play the flute and the fiddle. Growing up with two other musicians led to an emphasis on playing in groups rather than focusing solely on solo playing. She started on the concertina with Ann Dylan and studied with Lexie Boatright and Patty Furlong. Her style is influenced heavily by the playing of Caitlín Nic Gabhann and Mícheál Ó Raghallaigh.

Catrióna is a multiple Mid Atlantic Fleadh champion on the concertina and has competed several times in the All Ireland Fleadh. As a youth she played in ceili band and grupa cheoil competitions in the US and Ireland with the Pearl River School of Irish Music. She is the concertina and ceili band instructor for the Baltimore Irish Music School, and has taken multiple bands over to Ireland.

Catrióna has taught concertina at the Catskills Irish Arts Week, Baltimore Irish Trad Fest, and O'Flaherty Irish Music Retreat. She also had the privilege of teaching the concertina to and recording with Steve Martin for show 'Only Murders in the Building.'
