Bernard II of Haldensleben (or Bernhard) (died 1051) was the Margrave of the Nordmark from 1018 until his death.
He was the grandson of Dietrich of Haldensleben and a rival of the counts of Walbeck, one of whom, Werner, succeeded him in the march following his deposition.
[1] The Emperor intervened and forced Bernard I to pay Gero 500 lbs of silver in compensation for the assault his men had made on the city of Magdeburg.
He also left daughters, Theutberga, Oda, and perhaps Othelindis, wife of Dirk III, Count of Holland.
His illegitimate son by a Slav mistress, Otto, tried to succeed his brother, but was defeated and killed in battle.
