|Intro||Lord of Werle-Güstrow|
|Death||August 27, 1337|
John II, Lord of Werle[-Güstrow] nicknamed The Bald (after 1250 – 27 August 1337), was from 1309 to 1316 co-regent of Werle and from 1316 to 1337 Lord of Werle-Güstrow. He was the second eldest son of John I of Werle and Sophie of Lindow-Ruppin.
He reigned Werle from 1309 to 1316 together with his brother Nicholas II. After Nicholas's death in 1316 it was decided to divide the territory, and John took control over the part Werle-Güstrow and Nicholas's son John III, took control over the part Werle-Goldberg.
On 4 May 1326, King Christopher II of Denmark promised to invest John and Lord Henry II of Mecklenburg with the Principality of Rügen. However, the Dukes of Pomerania took Rugen, leading to the Rügen War of Succession. Pomerania successfully defended Rügen, and Mecklenburg's claims on Rügen could not be enforced.
He reduced his debts by prosecuting Jews for host desecration.
John died in 1337 and was buried in the Doberan Minster.
