Tårnholm is a manor house and estate at Korsør, Slagelse Municipality, Denmark.

Tårnholm was created when the former Antvorskov Cavalry District was divided into nine estates and sold in auction by the crown in 1774.

The largest of the estates, Tårnborg, was acquired by Christian Eggers for 26,000 Danish rigsdaler and renamed it Tårnholm.

The buyer was a consortium that consisted of count Vilhelm Carl Ferdinand Ahlefeldt-Laurvigen, Salomon Lindegaard and Rasmus Møller.

The end of the Napoleonic Wars and the Danish State Bankruptcy of 1913 was followed by a long agricultural crisis.

He had served as a naval officer during the Napoleonic Wars and later spent several years in Switzerland and France.

After his death in 1908, Tårnholm passed to his son Alexander Georg Tully Oxholm.
