Gerdrup, formerly Gjerup, is a manor house and estate located three kilometres north of Skælskør, Slagelse Municipality, Denmark.

After Anders Jacobsen Lunge's death in 1429, the ownership of Gerdrup seems to have been spread out on more than one simultaneous owner.

The estate was the subject of a legal dispute between Jørgen Rud, lensman of Saltø, and Jensen Sosadel Dyre.

Christian I ended up ruling in favour of Dyre, who had claimed that Gerdrup had been "in the custody of him and his parents in 16 and 40 years".

[2] During the Count's Feud, in 1535, Gerdrup is in a cover letter listed as belonging to Knud Rud, but Søren Stampe is later once again mentioned as the owner.

Ellen Hundermark married John Cunningham, a Scotsman who had served as captain of HDMS Trost on an expedition to Greenland.

Another Scotsman, David Welwood, who is buried at Eggeslevmagle Church, may also have owned a stake in the estate.

He died right after the marriage and Gerdrup was then transferred to the widow of his brother vice chancellor Holger Vinds, Margrethe Gjedde.

[4] In 1814, Henriette Elisabeth Schow married Peter Johansen de Neergaard but a prenuptual agreement secured both estates as her personal property.

Morten Qvistgaard commissioned the architect Gustav Friedrich Hetsch to design a new main building.

His son, Victor Emilius Qvistgaard, who inherited the estate when he was just four years old, constructed a new main building from another design by Rudolf Unmack in 1864–66.
