The Códice de Roda or Códice de Meyá is a medieval manuscript that represents a unique primary source for details of the 9th- and early 10th-century Kingdom of Navarre and neighbouring principalities. It is currently held in Madrid as Real Academia de la Historia MS 78.

The Real Academia de la Historia is a Spanish institution in Madrid that studies history "ancient and modern, political, civil, ecclesiastical, military, scientific, of letters and arts, that is to say, the different branches of life, of civilisation, and of the culture of the Spanish people". Spanish people in this regard are understood to be citizens of the Kingdom of Spain or the indigenous people of its predecessors, or their descendants. The academy was established by royal decree of Philip V of Spain on 18 April 1738.
