Oremandsgaard is a manor house and estate located seven kilometres south of Præstø, Vordingborg Municipality, in southeastern Denmark.

It is one of the oldest organic farms in Denmark and plays host to an annual chamber music festival.

Oremandsgaard is first mentioned in a letter of 1356, in which one "Pæther Bekære" cedes all his farms and the village of Gedhærudh (Gederød) to Valdemar IV.

It is believed that the main building was destroyed during the Dano-Swedish War in 1658–1660 due to finds of rubble and weapons in the surrounding fields and also because this was the case for nearby Jungshoved.

[1] In 1761, some ten years before Vordingborg Cavalry Fistrict was dissolved, Frederick IV presented Oremandsgaard and nearby Jungshoved to Henrik Brockenhuus.

It participated in the Danish East and West Indies trade with its own fleet of merchant ships.

The Hage family was known for their humane treatment of the peasants on their estates, building schools and hospitals and providing economic support for the sick..

It takes place in late July, lasts for a week and features young promising chamber musicians from Denmark and abroad.
