Øbjerggaard is a manor house and estate situated east of Køng, midway between Næstved and Vordingborg some south of Copenhagen, Denmark. One of 12 new manors created when Vordingborg Cavalry District was dissolved in 1774, it was initially the site of a textile factory established by Niels Ryberg. The current main building from the 1840s is now known as (New Øbjerggaard). The old headquarters of the textile factory, (Old Øbjerggaard), constructed by Ruberg in 1780 and listed on the Danish registry of protected buildings and places in 1945, is now home to Køng Museum. The current owner of the estate, Peter Eriksen Oxholm Tillisch, resides at Rosenfeldt, his other estate, while Ny Øbjerggaard is operated as a bed and breakfast.
