John II of Mecklenburg

John II (c. 1250–1299) was the youngest son of John I of Mecklenburg. After his father died he ruled Mecklenburg from 1264 jointly with his brothers.

When his elder brother Henry I was taken captive while on pilgrimage in 1275, John and his brother Nicholas III took over the regency and the guardianship of Henry's sons. From 1283 he is recorded as lord of Gadebusch, probably his apanage. John died on 12 October 1299.
