Minden-Lübbecke is a Kreis (district) in the northeastern part of North Rhine-Westphalia, Germany.

In the south of the district the river runs through a narrow gorge, which is formed by two mountain chains, the Wiehen Hills in the west and the Wesergebirge in the east.

At its biggest extent in the 13th century, it later lost territory until it came finally to be around the size of today's district.

Lost for a time to Napoleonic France, it came back to Prussia in 1813, and was then part of the Province of Westphalia.

After the district was merged with Lübbecke a second key was added, to symbolize the two historic parts.
