Helmold III, Count of Schwerin

Helmold III (before 1228 – c. 1296) was the son of Count Gunzelin III of Schwerin and Margaret of Mecklenburg. On his father's death in 1274 he inherited the Schwerin portion of the divided county. He married three times, taking Margaret of Schleswig as his wife in 1264.

His son by the first marriage, Gunzelin V, succeeded him in 1296, while Henry III, his son by Margaret, later held Boizenburg and Crivitz. Helmold last appears in a charter of 25 August 1295 and was dead by May 1296.
