Nuño Sánchez (Catalan: Nunó, Nunyó, or Nunyo Sanç, French: Nuno Sanche) (c. 1185 – 1242) was a nobleman and statesman in the Crown of Aragon.
Nuño was the son of Sancho, Count of Provence, Roussillon, and Cerdagne, and Sancha Núñez of the House of Lara.
In 1215 his father married him to Peronella, daughter of Bernard IV of Bigorre, but the marriage was annulled by Pope Honorius III the very next year (1216).
In 1220, Nuño had married Teresa López, daughter of Lope Díaz II de Haro, Lord of Biscay.
The troubadour Aimeric de Belenoi composed a planh on his death, significant of his reputation for courtliness and chivalry.
