The General Directorate for Internal Security (French: Direction générale de la sécurité intérieure, DGSI) is a French intelligence agency. It is charged with counter-espionage, counter-terrorism, countering cybercrime and surveillance of potentially threatening groups, organisations, and social phenomena.

The agency was created in 2008 under the name Central Directorate of Interior Intelligence (French: Direction centrale du renseignement intérieur, DCRI), merging the direction centrale des Renseignements généraux (RG) and the direction de la surveillance du territoire (DST) of the French National Police. It acquired its current name in 2014, with a small structural shift: contrary to the DCRI which was part of the National Police, the DGSI reports directly to the Ministry of the Interior.
