Agnes (Aragonese: Agnés) was a Queen of Aragon, the second wife of Ramiro I of Aragon. She is speculated to have been daughter of either William VI, Duke of Aquitaine or William VII, Duke of Aquitaine, and perhaps remarried to Peter I, Count of Savoy. Peter I, Count of Savoy, would later marry an "Agnes, daughter of William of Poitou", herself speculated to have been daughter of William VII. It is possible that this was the widowed Queen of Aragon, although if so, Agnes would have had to have married Ramiro at a very young age.
