Senior colonel is an army officer rank placed between a regular colonel and a major general. The rank typically exists in militaries that do not maintain a rank of brigadier general/brigadier.

In Nazi Germany, a rank equivalent to senior colonel, Oberführer, was used by both the SA and SS. In the branches of the Allgemeine SS (General SS) and Waffen-SS (Armed SS) the rank of Oberführer was widely used. The rank did not exist in the army (Heer), although the Kriegsmarine (navy) maintained the equivalent rank of Kommodore.
