The Direction de la Surveillance du Territoire (DST; English: Directorate of Territorial Surveillance) was a directorate of the French National Police operating as a domestic intelligence agency. It was responsible for counterespionage, counterterrorism and more generally the security of France against foreign threats and interference. It was created in 1944 with its headquarters situated at 7 rue Nélaton in Paris. On 1 July 2008, it was merged with the Direction centrale des renseignements généraux into the new Direction centrale du renseignement intérieur.

The DST Economic Security and Protection of National Assets department had units in the 22 regions of France to protect French technology. It operated for 20 years, not only on behalf of defense industry leaders, but also for pharmaceuticals, telecoms, the automobile industry, and all manufacturing and service sectors.

The Surveillance du Territoire (ST) was a counterintelligence and counter terrorism police service which was created in 1934 by the government of Gaston Doumergue and reinforced in 1937 by the government of the Popular Front. It enabled the arrest of many German spies during World War II. Several of its members went on to join the Resistance during the war. The DST succeeded the ST by an order of November 16, 1944, signed by General de Gaulle and relating to the organization of the Ministry of the Interior, supplemented by a decree of November 22, 1944. DST was entrusted to Roger Wybot, who was at the time head of General de Gaulle's counter-espionage section

According to a 2003 book, the DST has never been infiltrated by any foreign agency in all of its history.

During the Algerian War (1954–62), the agency created the Organization of the French Algerian Resistance [fr] (ORAF), a group of counter-terrorists whose mission was to carry out false flag terrorist attacks with the aim of quashing any hopes of political compromise. Reporter Marie-Monique Robin, author of a book investigating relationship between the Algerian War and Operation Condor, said to L'Humanité newspaper that "[the] French have systematized a military technique in urban environments which would be copied and pasted to Latin American dictatorships." Roger Trinquier's famous book on counter-insurgency had a very strong influence in South America. Robin was "shocked" to learn that the DST communicated to the Chilean DINA the name of the refugees who returned to Chile (Operation Retorno), all of whom were later killed.

On 3 December 1973, agents of the DST, disguised as plumbers, were caught trying to install a spy microphone in the offices of the Canard Enchaîné newspaper. The resulting scandal forced Interior Minister Raymond Marcellin to leave the government.

On 26 June 1975 Ilich Ramírez Sánchez, also known as Carlos the Jackal shot and killed Raymond Dous and Jean Donatini, two DST inspectors, and Michel Moukharbal, a Lebanese informant, on Rue Toullier in Paris. A third police officer, Jean Herranz, Commissioner of the DST, is seriously injured.

One of the greatest success of the DST was the recruitment of the Soviet KGB officer Vladimir Vetrov. Between the spring of 1981 and early 1982 he handed almost 4,000 secret documents over to the French, including the complete official list of 250 Line X KGB officers stationed under legal cover in embassies around the world, before being arrested in February 1982 and executed in 1985.
