The Five-seveN is a semi-automatic pistol manufactured by Fabrique Nationale de Herstal (FNH). Its name is derived from the unique ammunition it uses.

FN created the new 5.7x28mm cartridge for its FN P90 personal defense weapon to meet NATO requirements released in 2000. Subsequently FN created the Five-seveN pistol to offer agencies who adopt the P90, which is a sub-machine gun chambered for the same cartridge.

Though an effective weapon, the Five-seveN has not been widely adopted, due mostly to the rather unconventional concept and ammunition. Current users include several international special forces/counter-terrorist groups (including the French GIGN) and a large number of local police department SWAT teams (including some in the United States).
