Jovan Uroš Nemanjić (Serbian Cyrillic:Јован Урош Немањић) orJohn Ouresis Doukas Palaiologos orJoasaph ofMeteora (Greek:Ιωάννης Ούρεσης Δούκας Παλαιολόγος,romanized: Iōannēs Ouresēs Doúkas Palaiologos), was the ruler ofThessaly from c. 1370 to c. 1373, retiring as a monk for the next half century thereafter. He died in 1422 or 1423.^[1][2] By birth, he was member of theNemanjić dynasty, ruling family of theSerbian Empire.

John Uroš was the son of EmperorSimeon Uroš by his wife,Thomais Orsini. He was born in 1350 and died in 1422.^[3] His paternal grandparents wereStephen Uroš III andMaria Palaiologina His maternal grandparents wereJohn II Orsini andAnna Palaiologina.

Between 1369 and 1372 he succeeded his father as titularemperor of the Serbians and Greeks, although his rule was limited toThessaly. He may have been associated on the throne by his father as early as 1359/60. After reigning for an uncertain number of years, John Uroš abdicated in favour of his relative, theCaesarAlexios Angelos Philanthropenos, and became a monk.

He joined the monastic community founded by his father atMeteora, where he is documented under his monastic nameJoasaph in 1381. Although he had surrendered political power, John Uroš remained wealthy and influential. In 1384–1385 he helped his sisterMaria governEpirus after the murder of her husbandThomas II Preljubović. He endowed the monasteries atMeteora and eventually became the head of the local monastic community, rebuilding or establishing further monasteries in the area in 1388 and 1390. In the 1390s he visitedMount Athos, but was back in Meteora by 1401, and died there in 1422 or 1423.

John Uroš was the last emperor of Serbs and Greeks and the last Serbian ruler of Thessaly. His relativeAlexios Angelos Philanthropenos succeeded him and recognizedByzantinesuzerainty, and the area was lost toBayezid I of theOttoman Empire by his sonManuel Angelos Philanthropenos in 1394. John Uroš had a younger brother named Stefan Uroš, ruler of Pharsalus (sons ofSimeon Uroš), who may have heldPharsalos as his fief. Although he died long after his brother became monk, he did not succeed him as ruler ofThessaly.

John Uroš married a daughter ofRadoslav Hlapen, a Serbian lord in Macedonia, and his wife, Irina (Irene)Nemanjić. According to the manuscriptDell'Imperadori Constantinopolitani, preserved in the papers of Angelo Masarelli, the father of John's wife was "lord of Drima" ("l Signor Drimi"). John had five children, three sons and two daughters:^[4]
