Henry, Duke of Mecklenburg-Stargard (before 1412 – 26 May/20 August 1466) was the ruling Duke of Mecklenburg-Stargard, including the Lordships of Neubrandenburg, Stargard, Strelitz and Wesenberg, from 1417 to 1466.
Henry was born before 1412 as the youngest child of Duke Ulrich I of Mecklenburg-Stargard and his wife Margaret.
After John III's death, Henry ruled all of Mecklenburg-Stargard.
Thomas Kantzow called him "a wicked robber, who always bothers the Mark (i.e. Brandenburg) and the entire country all the way to Stettin, who was mad at all the cows, leaving Duke Joachim of Stettin wondering where he stored all the hides".
[1] During Henry's reign, the Peace of Wittstock was concluded, which permanently fixed the southeastern boundary of Mecklenburg.
