Tresor is the third solo studio album by Welsh singer Gwenno, released on 1 July 2022 by Heavenly Recordings. Like Gwenno's previous work, this album's lyrics are almost entirely in Cornish with one song, "N.Y.C.A.W." (which stands for "Nid yw Cymru ar Werth", meaning "Wales is not for Sale"), in Welsh. The album's name comes from the Cornish word for "treasure". The album was shortlisted for the 2022 Mercury Prize.
