John George of Ohlau (Polish: Jan Jerzy oławski) (17 June 1552 – 6 July 1592), was a Duke of Ohlau and Wohlau Wołów (since 1586 with his brother as a co-ruler until 1592).
He was the second son of George II the Pious, Duke of Brieg-Ohlau-Wohlau (Brzeg-Oława-Wołów), by his wife Barbara, daughter of Joachim II Hector, Elector of Brandenburg.
In 1586, after the death of his father, John George and his older brother Joachim Frederick inherited (as a co-rulers) only Ohlau and Wohlau, because Brieg was given by his late father to their mother Barbara until her own death. Both brothers settled their residence in Ohlau.
In Brzeg on 16 September 1582, John George married with Anna (Stuttgart, 12 June 1561 – Haynau (Chojnów), 7 July 1616), daughter of Christoph, Duke of Württemberg. They had two children:
On his death without surviving male issue, John George was succeeded by his brother Joachim Frederick, who became in sole ruler, but only in Wohlau, because Ohlau was given by John George's widow. Anna lost her land when she married again in 1594 with Duke Frederick IV of Liegnitz, and reverted to Joachim Frederick, who two months later also obtain Brieg when his mother Barbara died.
