Blessed Gertrude of Aldenberg O. Praem, (c. October 1227 – 13 August 1297) was a German noblewoman and abbess.

She became a Premonstratensian canoness regular at the Abbey of Aldenberg, near Wetzlar, in the Diocese of Trier, where she spent much of her life leading the community as its abbess.

Gertrude was scarcely two years old when her mother left her in the care of the canonesses of the Abbey of Aldenberg, where she later entered the community.

[2] With an inheritance she received from her uncle, Dietrich I, Margrave of Meissen, Gertrude erected a church and a poorhouse attached to the abbey.

Pope Clement VI permitted the abbey to celebrate her feast day[3] and granted indulgences to those who venerated her relics.
