The State Investigation and Protection Agency (SIPA; Serbo-Croatian: Državna agencija za istrage i zaštitu / Државна агенција за истраге и заштиту) is the national police intelligence and protective security agency of the Bosnia and Herzegovina responsible for clandestine and covert operations, countering hybrid threats, counterintelligence, counter-revolutionary, counterterrorism, executive protection (especially the Presidency of Bosnia and Herzegovina and visiting foreign leaders), intelligence gathering and assessment on threats to national security that are under the responsibility of the police authority, investigation and interrogation serious crimes, protects police operations classified information, and public security.

SIPA is under the direct administration of the Ministry of Security of Bosnia and Herzegovina.

After the war in Bosnia and Herzegovina and the Dayton Agreement, the first organisation with very limited law enforcement authorities was the Agency for Information and Protection of Bosnia and Herzegovina (Serbo-Croatian: Agencija za informacije i zaštitu Bosne i Hercegovine / Агенција за информације и заштиту Босне и Херцеговине), established in 2002. That independent agency was responsible for collecting data of interest related to international crimes and criminal legislation of Bosnia and Herzegovina, counterintelligence that are under the responsibility of the police authority, protection of VIPs as well as diplomatic and consular missions of Bosnia and Herzegovina, and public security.

In June 2004, today's SIPA was created out of the Agency for Information and Protection of BiH. It is under the Ministry of Security, but independent in operational matters.

Under the Law on State Investigation and Protection Agency and per other regulations, SIPA performs tasks within its jurisdiction throughout the state of Bosnia and Herzegovina. It is also the basic tool of stability and the tool for making the people of Bosnia and Herzegovina feel safe and secure from threats within the state.

The activities of SIPA include the arrests of persons who are suspected of committing war crimes, as well as successful investigations of money laundering activities, combating organized crime and terrorism, provision of witnesses with protection and support, and the formation and development of a special unit.

In March 2025, in response to the guilty verdict of Milorad Dodik issued by the Court of Bosnia and Herzegovina for violating Bosnia and Herzegovina's criminal law, the entity national assembly enacted a set of laws in an attempt to prohibit SIPA (among others) from acting on the territory of the entity. However, the Constitutional Court of Bosnia and Herzegovina has annulled the set of laws enacted, pending a full decision, as the result of an appellation raised by the member of the Presidency of Bosnia and Herzegovina Denis Bećirović.

SIPA started with just three employees, whereas today it has over 850 employees working in 11 organizational units at the headquarters of the agency and in four regional offices within the cities of Istočno Sarajevo, Tuzla, Banja Luka, and Mostar.
