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.

Žirmūnai is the most populous administrative division (elderate) in Vilnius. It is also a neighbourhood in the Lithuanian capital city Vilnius, encompassing the city district of the same name, built in the 1960s.
