Mécia Lopes de Haro or Mencía López de Haro (c.1215–1270) was a Castilian noblewoman, the wife successively of count Álvaro Pérez de Castro and of King Sancho II of Portugal. The subsequent annulment of her marriage by Pope Innocent IV has led to disagreement over whether she should be counted among the queens consort of Portugal. She played a central role in the Portuguese political crisis of 1245.


Mécia Lopes was born in Biscay, the daughter of Lope Díaz II de Haro, lord of Biscay, and of Urraca Alfonso of León. Her mother was an illegitimate daughter of Alfonso IX of León. She was thus niece of the reigning king, Ferdinand III of Castile.[citation needed]
