Rossum is a village in the Dutch province of Overijssel. It is a part of the municipality of Dinkelland, and lies about 4 km north of Oldenzaal on the road to Ootmarsum.
It was first mentioned in the late-10th century as Rohthem, and means "settlement near cleared forest". In 1840, it was home to 504 people.
The Hunenborg is a circular rampart to the north of Rossum. In 1916, remnants of wooden buildings were discovered at the site. Later a wooden dam dating from the 1150s was uncovered, and may be the location of a 10th century fortress of the Prince-Bishop of Utrecht.
In the rural environment some farms can be found in the traditional building style of the timber framed Low German house.
