The Warsaw Military District (Russian: Варшавский вое́нный о́круг) was a Russian military district of the Imperial Russian Army. It covered the territory of Congress Poland (without the part of Suwałki in Vilno Military District).
The Warsaw Military District was created in 1862. When World War I broke out, most of the units of the district (three out of its five infantry corps) were used to form the 2nd Army. Since the territory of the district was overrun by German and Austro-Hungarian armies in the course of 1915, it was dissolved, and its staff used in creating the new Minsk Military District.
