Nuno Mendes or Nuño Menéndez (died February 1071) was the last Count of Portugal from the family of Vímara Peres. The son of Count Mendo Nunes (Menendo Núñez), his desires for greater autonomy for Portugal led him to face King Garcia II of Galicia. On 18 February 1071 he fought in the Battle of Pedroso, near the Monastery of São Martinho de Tibães, and his defeat and death led the winning Garcia II to call himself King of Galicia and Portugal. The County of Portugal was then subsumed into the crowns of Galicia and León until regranted by King Alfonso VI of León and Castile a quarter-century later.
