James II, King of Aragon (10 August 1267 – 2 November 1327), in Spanish Jaime II, in Catalan Jaume II, also James II of Barcelona, called The Just (Catalan: El Just) was the second son of Peter III of Aragon and Constance of Sicily.

He succeeded his father as King of Sicily in 1285, and was then known as "James I of Sicily." Upon his brother Alfonso III's death in 1291, he succeeded also to the throne of Aragon. By a peace treaty with Charles II of Anjou in 1296, he agreed to give up Sicily, but the Sicilians instead installed on the throne his brother Frederick. He reigned in Aragon until his death in 1327.

He married four times. His first wife was Elizabeth of Castile, daughter of Sancho IV of Castile, but that marriage was dissolved after Sancho's death, when James choose to change his alliances and take advantage of the turmoil inside Castile. His second wife was Blanca of Anjou, daughter of his family's rival Charles II of Naples. They married in 1295 and she was mother of his legitimate children. He had no children from his later marriages to Marie of Cyprus, daughter of Hugh III of Cyprus, in 1315, and to the Catalan noblewoman Elisenda of Montcada in 1322.
