Ressen is a village in the municipality of Lingewaard in the province of Gelderland, the Netherlands. Part of Ressen is now a neighbourhood of Nijmegen.
Ressen was first mentioned in 1150 as Rexnam. The etymology is unknown and may not be Germanic. In 1840, it was home to 200 people. In 1997, a part of Ressen was transferred to Nijmegen for the neighbourhood. For a short period, it had the place name Ressen (Nijmegen), however it has become an integral part of the new neighbourhood.
