Juan Ruiz (ca. 1283 – ca. 1350), known as the Archpriest of Hita (Arcipreste de Hita), was a medieval Spanish poet. He is best known for his ribald, earthy poem, Libro de buen amor (The Book of Good Love). He was born either in Alcalá de Henares, or perhaps Alcalá la Real, a village of Jaén, then part of al-Andalus, or Muslim Spain. Little is known about him today, save that he was a cleric and probably studied in Toledo. Though his birth name is known to be Juan Ruiz, he is widely referred to by his title of "Archpriest of Hita."
