John II, Prince of Anhalt-Zerbst

John II, Prince of Anhalt-Zerbst (died 11 April 1382) was a German prince of the House of Ascania and ruler of the principality of Anhalt-Zerbst.

He was the youngest son of Albert II, Prince of Anhalt-Zerbst, by his second wife Beatrix, daughter of Rudolf I, Elector of Saxony and Duke of Saxe-Wittemberg.

The death of his older brother Albert III in 1359 made John his father's sole heir; his older brother Rudolf was an ordained priest.
