Feuerwerker (ordnance technician or specialist, literally 'fire worker') are specialists in the armed forces of German-speaking countries responsible for the maintenance of ammunition.

From the late Middle Ages until the Early modern period a Feuerwerker was a highly specialised artisan with detailed knowledge of the closely guarded secrets of making gunpowder. Since the 19th century Feuerwerker became a distinguished career in Austrian, German and Russian (Russian: Фейерверкер; Feyerverker) armed forces.

In the modern German Bundeswehr, Feuerwerker is the collective designation to non-commissioned officers (OR5 to OR9) and officers of the military functional service (German: Offizier(e) militärfachlischer Dienst, OF1 and OF2) with several years of special training pertaining to construction, maintenance, and destruction of ammunition.
