Committee for State Security of the Latvian Soviet Socialist Republic

Committee for State Security of the Latvian Soviet Socialist Republic (Latvian: Latvijas Padomju Sociālistiskās Republikas Valsts drošības komiteja; Russian: Комитет государственной безопасности Латвийской ССР) or KGB of LSSR (Latvian: VDK) was the secret police and state security organization of the Latvian Soviet Socialist Republic.

Legally and hierarchically, the Security Committee was subordinate to the Council of Ministers of the Latvian SSR as well as the KGB as a territorial unit.

Both full-time and freelance employees of the committee were commonly referred to as "Chekists".

It was controlled by the Soviet KGB and was established on April 10, 1954 and dissolved on August 24, 1991.
