Risbyholm (1721–1904: Benzonseje) is a manor house located in Roskilde Municipality, near Havdrup, some 30 km southwest of Copenhagen, Denmark.

[1] The manor was founded as Benzonseje in 1721 when Peder Benzon, a Supreme Court justice, obtained the king's permission to merge several farms.

In 1838, Risbyholm was sold for 10,020 Danish eigsdaler ro Kirstine Catharine Schumacher (née Leegaard).

[1] In 1787, John Brown, a Scottish-born merchant and ship owner, purchased the property in auction for 60,000 Danish rigsdaler.

[1] Anna Hebert, the widow after the previous owner, Christian Frederik Harald, changed the name of the property to Risbyholm in 1903.
