The Estonian Internal Security Service (Estonian: Kaitsepolitsei, officially Estonian: Kaitsepolitseiamet, abbreviated KAPO) is the central national security agency of the Republic of Estonia. Its primary responsibilities include protecting the constitutional order, conducting counterintelligence, and investigating specific criminal offenses. These include crimes committed by state officials, acts of terrorism, incitement to hatred, crimes against humanity, war crimes, and the illegal handling or trafficking of firearms, explosives, radioactive substances, and other strategic materials. The agency also protects state secrets and performs other internal security functions.

The Estonian Internal Security Service operates under the authority of the Estonian Ministry of Internal Affairs. While many of its activities remain classified, the agency publishes an annual overview of the national security situation, titled the Kaitsepolitsei aastaraamat.
