Ugone II of Arborea

Ugone II (died 1335) was Judge of Arborea from 1321, the illegitimate son of Marianus III and Padulesa de Serra. He became vassal of James II of Aragon, whom the pope had invested with Sardinia and Corsica in exchange for renouncing Sicily, hoping to rule the island as the Catalan crown's governor. In 1323–1324 he aided the future Alfonso IV's conquest, which expelled Pisa from Sardinia.

With his wife Benedetta he had nine children. He died of illness at Sardara on 5 April 1335 and was succeeded by his son Peter III.
