Dosenbek is an {{convert|8|km|mi|adj=mid|-long}} 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.
