The Reich Main Security Office (German: Reichssicherheitshauptamt or RSHA) was an organization subordinate to Heinrich Himmler in his dual capacities as Chef der Deutschen Polizei (Chief of German Police) and Reichsführer-SS, the head of the Nazi Party's Schutzstaffel (SS). The organization's stated duty was to fight all "enemies of the Reich" inside and outside the borders of Nazi Germany.

The RSHA was created by Himmler on 27 September 1939. Himmler's assumption of total control over all security and police forces in Germany was the "crucial precondition" for the establishment and growth of the SS state. He combined the Nazi Party's Sicherheitsdienst (SD; SS intelligence service) with the Sicherheitspolizei (SiPo; "Security Police"), which was nominally under the Interior Ministry. The SiPo was composed of two sub-departments, the Geheime Staatspolizei (Gestapo; "Secret State Police") and the Kriminalpolizei (Kripo; "Criminal Police"). The RSHA was often abbreviated to "RSi-H" in correspondence to avoid confusion with the SS-Rasse- und Siedlungshauptamt (RuSHA; "SS Race and Settlement Office").

The creation of the RSHA represented the formalization, at the top level, of the relationship under which the SD served as the intelligence agency for the security police. A similar coordination existed in the local offices. Within Germany and areas which were incorporated within the Reich for the purpose of civil administration, local offices of the Gestapo, criminal police, and SD were formally separate. They were subject to coordination by inspectors of the security police and SD on the staffs of the local higher SS and police leaders, however, and one of the principal functions of the local SD units was to serve as the intelligence agency for the local Gestapo units. In the occupied territories, the formal relationship between local units of the Gestapo, criminal police, and SD was slightly closer.

Throughout the course of wartime expansion, the RSHA continued to grow at an enormous rate and was "repeatedly reorganized". Routine reorganization did not change the tendency for centralization within the Third Reich nor did it change the general trend for organizations like the RHSA to develop direct relationships to Hitler, adhering to a familiar National Socialist pattern of the leader-follower construct. For the RSHA, its centrality within Nazi Germany was pronounced since departments like the Gestapo (within the RSHA) were controlled by Himmler and his immediate subordinate SS-Obergruppenführer and General of Police Reinhard Heydrich; they held the power of life and death for nearly every German and were essentially above the law.
