Ørholm is a neighbourhood and locality on the Mølleåen river in Lyngby-Taarbæk Municipality in the northern suburbs of Copenhagen9, Denmark.

Ørholm Watermill has a history that dates back to at least the 15th century but the current industrial buildings were constructed after fires in 1886 and 1913.

The watermill is mentioned in the Roskilde Bishop's Census Book (Roskildebispens Jordebog) from the 1370s as molendinum Ørewaz while the locality at this point was known as Ørevad.

In 1854, Ørholm and Nymølle were sold to the owners of Strandmøllen and became part of a Danish de facto paper monopoly.

The architect or exact time of construction is unknown but it is assumed that it was built for Lauritz Stubs since it is known that he applied for permission to transport a large load of bricks through Jægersborg Dyrehave in 1753.

From 1866, Christian Drewsen's daughter Ophelia took over the house, together with her husband, the National Liberal editor Godske Nielsen.
