John II of Mecklenburg ( - 12 October 1299) was from 1264 until his death Lord of Mecklenburg.
He was the youngest son of John I and Luitgard of Henneberg (1210-1267), the daughter of Count Poppo VII of Henneberg. After his brother Henry I was taken prisoner during his pilgrimage, he took over the regency of Mecklenburg and the guardianship of Henry's sons in 1275, along with his brother Nicholas III.
