Eleanor of Sicily

Eleanor (1325–1375) was a Sicilian princess, daughter of King Peter II of Sicily and Elisabeth of Carinthia. In 1349 she married King Peter IV of Aragon as his third wife, becoming its queen consort and holding strong influence at court.

In 1357 she backed an unsuccessful plan to send Aragonese aid to her brother Frederick IV of Sicily in exchange for the Duchy of Neopatras. Her sons John I and Martin I both became kings of Aragon, and she died in 1375.
