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, and the company's initials "FN".

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 as a side arm using the same cartridge.
