Fernando (or Fernán) Pérez de Traba (c.1090–1 November 1155), also Fernão Peres de Trava ([fɨɾˈnɐ̃w̃ ˈpeɾɨʒ dɨ ˈtɾavɐ] or [ˈtɾavə]) in Portuguese, was a nobleman and count of the Kingdom of León who for a time held power over all Galicia. He became the lover of Countess Teresa of Portugal, through whom he attained great influence in that domain, and was the de facto ruler of the County of Portugal between 1121 and 1128. The Poema de Almería, a Latin poem celebrating one of Alfonso VII's major victories of the Reconquista, records that "if one were to see him [Fernán], one would judge him already a king."
