Obermehnen is a village in the German state of North Rhine-Westphalia in the county of Minden-Lübbecke. The village belongs administratively to the town of Lübbecke. Obermehnen has 1,360 inhabitants and an area of 9.6 km². At around 137 people per km² Obermehnen has the lowest density of all of Lübbeck's districts, not least because 4.3 km², i.e. 45%, of the parish area consists of uninhabited hill forest on the Wiehen Hills. Obermehnen is thus the most wooded part of the borough of Lübbecke.
