Yolande of Aragon or Violante of Sicily (Kingdom of Sicily – 1428, Italian: Jolanda d'Aragona, Catalan: Violant d'Aragó, Spanish: Violante de Aragón) was the legitimized daughter of King Martin I of Sicily and countess of Niebla. She was a member of the House of Barcelona. Eugénie de Montijo, the last Empress consort of the French, was descended from her.^[1]

She was the only daughter of King Martin I of Sicily and Sicilian noblewoman Agatuccia Pesce. She was born out of wedlock in Sicily. Before Blanche I of Navarre arrived in Sicily to be married to her father, the king sent her and her younger brother Fadrique (illegitimate son of Martin I and Tarsia Rizzari) to the Aragonese court to be reared in the care of the king's mother, Queen Maria de Luna.^[2] She was twice married. Her first husband was Enrique Pérez de Guzmán, 2nd Count de Niebla, whom she married in 1405. This marriage produced no issue and was annulled.^[3] Her second marriage was to Martín Fernández de Guzmán, son of Alvár Pérez de Guzmán, 6th Lord of Orgaz. She gave birth to three daughters.^[4] She died in 1428.
