Rodrigo de la Guitarra ("Rodrigo of the gittern") was a Spanish lutenist and gittern player, active primarily in the first half of the fifteenth century. Rodrigo was in the service of the House of Trastámara, and was a court composer for Ferdinand I of Aragon when he received the Crown of Aragon in 1412. At Ferdinand's death in 1416, Alfonso V was crowned King of Aragon, and Rodrigo remained in his service under the title ministril de camara. He was sent to visit the Count of Foix and the courts of Navarre and Castile, accompanied by Diego, a singer who also served the Aragonese royalty.
