Ramiro Sánchez of Monzón

Ramiro Sánchez of Monzón (c. 1070–1129/1130) was a Navarrese noble, the son of Sancho Garcés, an illegitimate son of King García Sánchez III of Navarre. After his uncle Sancho IV was killed in 1076 and Navarre was partitioned between Castile and Aragon, he was raised at the Aragonese court.

As a royal tenente he held Monzón and Tudela between 1104 and 1129. Around 1098 he married Cristina Rodríguez, a daughter of El Cid, and in 1099 escorted the Cid's body to Cardeña. His son García Ramírez succeeded him at Monzón and became king of Navarre.
