The 7.62×25mm Tokarev cartridge (designated as the 7,62 × 25 Takorev by the C.I.P.) is a Russian rimless bottlenecked pistol cartridge widely used in former Soviet satellite states, China and Pakistan among other countries. The cartridge has since been replaced in most capacities by the 9×18mm Makarov in Russian service.

Prior to the First World War, the 7.63×25mm Mauser C96 pistol gained in popularity worldwide. In 1908, the Tsarist army placed the C96 on a list of approved sidearms that officers could purchase at their own expense in lieu of carrying the Nagant M1895 revolver. Between 1914 and 1917, more Mauser pistols and ammunition were obtained as captured arms from German and Turkish forces. The Mauser and its cartridge were used on all fronts of the Russian Civil War and in the 1920s, during a period of relatively close cooperation between Soviet Russia and the Weimar Republic, the Red Army purchased batches of the smaller Bolo version as well as ammunition for use by its officers. Although a copy of the cartridge was being produced at the Podolsky Ammunition Factory, the Soviets eventually purchased a license and manufacturing equipment from DWM in Germany to produce the cartridge. In 1929, the Soviet Artillery Committee made a proposal to develop a domestic pistol chambered for the Mauser cartridge. After considerable research and development, it was decided that the "Model 1930 7.62 mm Pistol Cartridge," essentially the Mauser round with minor modifications, was to become the standard caliber for Soviet pistols and submachine guns. Early versions of the Vasily Degtyaryov-designed PPD-40 submachine gun were marked "For Mauser Cartridge Caliber 7.62 mm".
