John Henry IV of Gorizia (1322–1338) was a medieval Count of Gorizia and a member of the Meinhardiner dynasty. He was the only surviving son of Henry III and his wife Beatrix of Lower Bavaria, the daughter of Duke Stephen I. He succeeded his father as Count of Gorizia in 1323. Because he was still a minor, his mother and his uncles Albert II of Gorizia and later Henry of Carinthia acted as regents. After 1329, the custody was taken over by his cousin Albert III. Since he died young, he never actually reigned himself. Nevertheless, in 1332, aged nine, he was elected as podesta of Trieste, in the city's attempt to forge an alliance with Gorizia against Venetian expansion.
