Fernando (or Fernán) Pérez de Traba (Spanish: [feɾˈnando ˈpeɾeθ ðe ˈtɾaβa, feɾˈnam -]; c. 1090 – 1 November 1155), or Fernão Peres de Trava (Portuguese: [fɨɾˈnɐ̃w ˈpeɾɨʒ ðɨ ˈtɾavɐ]), 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."
