Barnim IV of Pomerania

Barnim IV (1325 – 22 August 1365) was a duke of Pomerania-Wolgast, the second son of Duke Wartislaw IV. He was barely a year old when his father died in 1326, and he and his brothers Bogislaw V and Wartislaw V ruled jointly, first under guardianship and from 1341 in person.

In 1348 Emperor Charles IV granted him imperial immediacy. His sons Wartislaw VI and Bogislaw VI took part in the 1368 partition of Pomerania-Wolgast after his death.
