The 7.65×53mm Mauser (designated as the 7,65 × 53 Arg. by the C.I.P.) is a first-generation smokeless powder rimless bottlenecked rifle cartridge developed for use in the Mauser Model 1889 rifle by Paul Mauser of the Mauser company. It is also known as 7.65×53mm Argentine, 7.65×53mm Argentine rimless, 7.65mm Argentine, 7.65×53mm Belgian Mauser or 7.65mm Belgian (in the United States) and 7.65×53mm Mauser (in Belgium).

The 7.65×53mmR is a rimmed variant of the 7.65×53mm Mauser cartridge. Ballistically it is comparable to the also-rimmed .303 British cartridge.

The 7.65×53mm Mauser was the result of considerable experimentation by Paul Mauser to optimize the bullet diameter whilst using than new smokeless propellant introduced as Poudre B in the 1886 pattern 8mm Lebel that started a military rifle ammunition revolution. At the time of its development it was a high-performance smokeless-powder cartridge.

This cartridge was loaded commercially by many manufacturers in the United States until about 1936.Hornady is the only major U.S. ammunition manufacturer to still produce this cartridge. Sporting ammunition in this caliber is still loaded in Europe.Norma, Prvi Partizan, Sako and Fabricaciones Militares (FM) currently produce 7.65×53mm ammunition. For reloading the cartridge, use .303" British load data.

The 7.65×53mm Mauser has 3.70 ml (57.1 grains H₂O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt action rifles and machine guns alike, under extreme conditions.
