The Watermill at Kollen (Dutch: Collse Watermolen) is a watermill along the river Kleine Dommel, located on the Collseweg 1 in 't Coll, Eindhoven, in the province of North Brabant, Netherlands.

The watermill complex was made up out of two buildings, operating two undershot water wheels.

The gristmill and oil mill are both still in functioning order and are used on a small scale.

The Dutch painter Vincent van Gogh lived in nearby Nuenen from 1883 until 1885.

The mill was listed as a national monument (nr 14648) on 14 August 1972.
