John II (3 March 1455 – 25 October 1495), called the Perfect Prince (o Príncipe Perfeito), was the king of Portugal and the Algarves from 1477/1481 to 1495. 

Regarded as one of the greatest Portuguese rulers, chiefly because of his ruthless assertion of royal authority over the great nobles and his resumption of the exploration of Africa and the quest for India.

He suffered a long illness and died in 1495 at the castle of Alvor in the province of Algarve. John’s exercise of personal power, particularly against the nobles, explains the epithet the Perfect Prince, which owes its origin to Lope de Vega’s play about him.
