Constance of Sicily (1249 – 9 April 1302) was Queen of Aragon as the wife of King Peter III. She was the only daughter of King Manfred of Sicily and his first wife, Beatrice of Savoy.

On 13 June 1262, Constance married Peter, eldest son of King James I of Aragon. Her father was killed in the Battle of Benevento (26 February 1266) while fighting against his rival, Charles of Anjou. She inherited his claim to the Sicilian throne.

James I died on 27 July 1276 and Peter succeeded to the throne, with Constance as queen. During the War of the Sicilian Vespers (1282–1302), Peter and then their sons claimed the throne of Sicily in her right. The war resulted in the partition of the Kingdom of Sicily and the creation of the Kingdom of Trinacria under her heirs and the Kingdom of Naples under the heirs of Charles of Anjou.

Peter III died on 2 November 1285. Constance died as a nun in Barcelona.
