Guidantonio da Montefeltro
(1377 - February, 1443) was count of Urbino
in Italy from 1403 until his death.
In 1403, at the death of his father Antonio, Guidantonio inherited the family lands in the region of Italy called the Marche. Later he abandoned the Papal suzerainty and allied with King Ladislas of Naples, who made him Grand connestabile of the Kingdom of Naples in 1411. Excommunicated by Pope Gregory XII, he took advantage of that move to conquer Assisi.
Guidantonio later reconciled with Pope Martin V and with his enemy, the condottiero Braccio da Montone. In 1427 he occupied Urbania.
He died in 1443, his son Oddantonio succeeding him in Urbino.
