Gonzalo Rodríguez Girón, also known as Gonzalo Ruiz Girón, firstborn son of Rodrigo Gutiérrez Girón and María de Guzmán, was one of Castile's wealthiest and most powerful nobles. He was based in Tierra de Campos, and was among the most loyal supporters of King Alfonso VIII of Castile, Berengaria of Castile, and later of King Ferdinand III.

Rodrigo Gutiérrez Girón was a magnate and ricohombre from Palencia who played a key role in the Medieval history of the Iberian Peninsula. He was the first one of his lineage to add Girón to his patronymic. Owner of vast holdings and estates, Rodrigo and his relatives formed one of the most powerful clans in Tierra de Campos since the time of the Banu Gómez.
