James II (born c. 1264—died Nov. 3, 1327, Barcelona, Aragon [Spain]) was the king of Aragon from 1295 to 1327 and king of Sicily (as James I) from 1285 to 1295.
At the death of his father, Peter III, on Nov. 11, 1285, James inherited Sicily, and his elder brother became Alfonso III of Aragon, Catalonia, and Valencia. When his brother died (1291) he inherited Aragon and resigned Sicily (1295), marrying Blanche, daughter of Charles II of Naples, in an endeavour to make peace with the Angevins. Sardinia and Corsica were both assigned to him in compensation for Sicily, but he was able to occupy Sardinia only (1324). He was succeeded by his son Alfonso IV.
