Regintrud, also known asReginlind andRegentrud, (born 660–665,^[1] died 730–740) was probably the wife of DukeTheodbert of Bavaria or of his father DukeTheodo of Bavaria.^[2] A possibly identicalRegintrud becameabbess of Nonnberg Abbey in 720–725. However, details about her ancestry and life are widely disputed among historians.

According to differing views, Regintrud was either a daughter of KingDagobert I,^[1] or ofPfalzgrafHugobert andIrmina of Oeren, or ofChildebert III.

Assuming she was married with Theudebert of Bavaria, her children from this marriage were:

• Hugbert of Bavaria, heir to the duchy
• Guntrud, wife ofLiutprand

Historians researched inconclusive evidence about further children, such as a daughter named Pilitrud from a previous marriage with an unknown husband.Tassilo II andSwanachild are also suggested as children from her marriage with Theudebert.
