Gil Álvarez Carrillo de Albornoz (Italian: Egidio Albornoz) (1310 – 23 August 1367) was a Spanish cardinal and ecclesiastical leader.
Albornoz was born at Carrascosa del Campo, (Cuenca) early in the 14th century. He was the son of Gil Állvarez de Albornoz and of Doña Teresa de Luna, sister of Jimeno de Luna, archbishop of Toledo and a member of the prominent Carrillo family. He was educated at Zaragoza, while his uncle was bishop of that see, and studied law at Toulouse.
The powerful influence of his family opened him a public career early in life. He was made archdeacon of Calatrava, and became a member of the king's council while young. In 1338 he was chosen archbishop of Toledo in succession to his uncle by the favour of the king, Alfonso XI of Castile. At the battle of Rio Salado he successfully fought against a Marinid invasion from Morocco in 1340, and at the taking of Algeciras in 1344 he led the armed levy of his archbishopric.
As Archbishop of Toledo he held two reform synods; one at Toledo in May 1339, the other at Alcalá in April 1347. In 1343 he had been sent to Pope Clement VI at Avignon to negotiate a grant of a tax on the revenues of the Church for the Crusade. Albornoz left Spain on the death of the king Alfonso XI in March 1350, and never returned. It has been said, but not on contemporary evidence, that he fled from fear of Pedro of Castile. His military and diplomatic ability became known to the pope, who made him a cardinal-priest of S. Clemente in December of that year, at which point he resigned the archbishopric of Toledo.
