Peter IV of Aragon (1319-1387), king of Aragon (1336-1387), the Ceremonious or el del punyalet (the one of the little dagger). He deposed James III of Majorca and rejoined the Balearic Islands and Roussillon under the crown of Aragon. He wrote the Chronicle of his name.

Since 1356, he engaged with Peter I of Castile in what was called the "War of the Two Peters". It ended in 1375 with the Treaty of Almazán, without a winner due to the Black Death and several natural disasters.

Throughout his reign, Peter IV had frequent conflicts with the inquisitor general of Aragon, Nicolau Aymerich.

During his reign, the Generalitat was instituted in the Courts of 1358-1359.
