The .32 S&W Long is a straight-walled, centerfire, rimmed handgun cartridge, based on the earlier .32 S&W cartridge. It was introduced in 1896 for Smith & Wesson's first-model Hand Ejector revolver. Colt called it the .32 Colt New Police in revolvers it made chambered for the cartridge.

The .32 S&W Long was introduced in 1896 with the company's first hand ejector revolver. The .32 Long is simply a lengthened version of the earlier .32 S&W. The hand ejector design has evolved some, but with its swing out cylinder on a crane, has been the basis for every S&W revolver designed since. In 1896, the cartridge was loaded with black powder. In 1903 the small hand ejector was updated with a new design. The cartridge stayed the same, but was now loaded with smokeless powder to roughly the same chamber pressure.

When he was the New York City Police Commissioner, Theodore Roosevelt standardized the department's use of the Colt New Police revolver. The cartridge was then adopted by several other northeastern U.S. police departments. The .32 Long is well known as an unusually accurate cartridge. This reputation led Police Commissioner Roosevelt to select it as an expedient way to increase officers' accuracy with their revolvers in New York City. The Colt company referred to the .32 S&W Long cartridge as the .32 "Colt's New Police" cartridge, concurrent with the conversion of the Colt New Police revolver from .32 Long Colt. The cartridges are functionally identical with the exception that the .32 NP cartridge has been historically loaded with a flat nosed bullet as opposed to the round nose of the .32 S&W Long.

In the United States, it is usually older revolvers which are chambered in this caliber. The cartridge has mostly fallen out of use due to smaller revolvers chambered in .38 S&W Special being more effective for self-defense.
