Tuskulėnai Manor is a neoclassical manor in Žirmūnai elderate of Vilnius, Lithuania. It is best known as burial grounds of people executed by the KGB in 1944–1947. After Lithuania regained independence in 1990, the manor was reconstructed and the park was transformed into a memorial to the victims of Soviet repressions. It is administered by the Lithuanian Genocide and Resistance Research Center.

The centre was founded on 25 October 1992 by the Supreme Council of the Lithuanian Republic as the "State Genocide Research Centre of Lithuania".
