Dosenbek is an 8adj=midNaNadj=mid river of Schleswig-Holstein, Germany.
The origin is in the Gehege Negenharrie (Gehege may be translated as forest enclosure) in the district Rendsburg-Eckernförde. Most of the water originates from the Dosenmoor. The mouth is close to the Brachenfelder Gehölz in the district Brachenfeld of Neumünster. Here the Dosenbek empties into the Schwale.
