Rodrigo González de Lara (floruit 1078–1143) was a Castilian nobleman of the House of Lara. Early in his career he ruled that half of Asturias allocated to Castile. He was faithful to the crown throughout the reign of Queen Urraca (1109–26), during which time he was married to the queen's half-sister and ruled a large part of the old County of Castile. He and his elder brother, Pedro González, led the opposition to Alfonso VII early in his reign (1126–57). He led a revolt in 1130 and was exiled in 1137. He was a leader in the Reconquista—about which the contemporary Chronica Adefonsi imperatoris has much to say—and also took part in the military activities of the Crusader states on two occasions. He travelled widely throughout Spain, but ended his days in Palestine.
