Groupe d'intervention de la gendarmerie nationale

The GIGN ( ; ) is the elite tactical unit of the French National Gendarmerie. Among its missions are counterterrorism, hostage rescue, surveillance of national threats, protection of government officials, critical site protection (such as French embassies in war-torn countries), and targeting organized crime.

Established in 1973 and becoming operational in 1974, the GIGN was initially created as a relatively small tactical unit specialized in sensitive hostage situations, but has since grown into a larger force with expanded responsibilities and capabilities. It is now composed of nearly 1,000 operators. The main unit comprises around 400 operators based in Satory, near Versailles in the Paris Region. Approximately 600 additional operators make up fourteen regional GIGN branches called AGIGNs (), seven of which are also located in metropolitan France and the remaining seven, in French overseas territories. The unit shares jurisdiction of French sovereign territory with the special response units of the National Police, and its training centre is located in Beynes.
