Ramiro Sánchez of Monzón (1070–1116) was a noble kinsman of the kings of Navarre, and lord of the town of Monzón, Spain.
His father was Sancho Garcés, an illegitimate son of king García Sánchez III of Navarre. His mother was Constance, whose parentage has been subject to recent speculation - associated with the lords of Marañon in traditional sources, she has lately been suggested to have been daughter of queen Estefanía, King García's wife, and hence stepsister of her husband.
With the fall of his uncle, king Sancho IV of Navarre, the kingdom was divided between Castile and Aragon, and the royal family parceled out between the two. Ramiro was thus raised at the Aragonese court, and was lord of Monzón, in which he was succeeded by his eldest son, the future king García Ramírez of Navarre.
Ramiro was married to Cristina Rodríguez, daughter of Rodrigo Díaz de Vivar. Their children were:
García Ramírez (the Restorer), King of Navarre
Elvira, wife of count Rodrigo Gómez and mother of Gonzalo Ruiz of Bureba
