Hiltrud is a feminine Old High German name formed from hild, “battle,” and drud/þrūð, “strength.”
It was borne by two prominent eighth-century figures: Princess Hiltrud of the Franks, daughter of Charles Martel, who married Duke Odilo of Bavaria and later served as regent for their son Duke Tassilo III, and Saint Hiltrude of Liessies, a Frankish noblewoman venerated in northern France and Belgium.
The name remained in use throughout the medieval German-speaking world and saw a modest revival in the late nineteenth and early twentieth centuries, though it is now rare and considered old-fashioned.
In Austria, the designated name-day is September 27th.
Traditional German diminutives and familiar forms include: Hilde, Hildi, Trude, Trudi, and Trudel.

Other forms include:
- Hiltrude (Dutch, French, Italian)
