The SIG Sauer P239 is a semi-automatic pistol designed and manufactured by SIG Sauer—both SIG Sauer GmbH in Germany and SIG Sauer Inc. of New Hampshire, United States. It was produced from 1996 to 2018, and offered in three calibers: 9×19mm Parabellum, .357 SIG and .40 S&W. The P239 became popular in the United States as a concealed carry pistol.

The P239 has a 91 mm barrel with an overall length of 168 mm and height of 132 mm, weighing approximately 710–770 g (25–27 oz) empty, depending on caliber. The included single-stack magazine has a capacity of 8 rounds (9×19mm) or 7 rounds (.357 SIG or .40 S&W).
