The SIG P210 (Swiss Army designation Pistole 49, the civilian model was known as SP47/8 prior to 1957) is a locked breech self loading, semi-automatic pistol designed and manufactured in Neuhausen am Rheinfall (Canton of Schaffhausen, Switzerland) by SIG from 1948 to 2006.

It is of all-steel construction chambered in 9×19mm Parabellum and 7.65×21mm Parabellum. It was used from 1949 to 1975 by the Swiss Army and police units. It was also adopted and is still in service with the Military of Denmark (as M/49 Neuhausen or simply Neuhausen), in 1951 by the German Bundespolizei and in shooting sports.

The pistols were decommissioned by the Swiss Army and replaced by the SIG Sauer P220 (Swiss Army designation Pistole 75) developed in 1975. Swiss production of the P210 continued until 2006. A new model, the P210 Legend, was introduced by SIG Sauer GMBH of Germany in 2010, and another, the P210A, was introduced by SIG Sauer Inc. of New Hampshire in the United States in 2017. In 2022, Sig Sauer released the P210 Carry originally debuted at the 2010 Shot Show in Las Vegas, Nevada. The P210 Carry is a pistol chambered in 9x19 Parabellum with a capacity of 8+1. The P210 Carry is lighter and smaller than the original P210 featuring an alloy frame and a 4.1 inch barrel instead of the 4.7 inch barrel on the original P210. It also differs because it has new additions such as the front slide serrations, the Nitron finish, and the black Hogue G10 grips, for a more aggressive and modern look.
