Saint Madelberte of Maubeuge (or Machtelberthe; died c. 705) was a 7th-century nun related to the Merovingian dynasty.

She became abbess of Maubeuge Abbey in the County of Hainaut, now in northern France near the Belgian border.

[1] The hagiographer Alban Butler wrote in his Lives of the Fathers, Martyrs, and Other Principal Saints (1866), St. Madelberte, V.

ABBESS of Maubeuge, niece to St. Aldegundis, (honoured on the 30th of January,) she had the happiness to be educated in her monastery with her sister Aldetrudis, who, upon the death of her aunt, was chosen second abbess of Maubeuge, and succeeded by her sister Madelberte.

Her relics were translated from Maubeuge to Liege by St. Hubert about the year 722.
