Mariya Timofeevna Kislyak (Russian: Мария Тимофеевна Кисляк; 6 March 1925 – 18 June 1943) was a Soviet partisan and the leader of a Kharkov underground Komsomol cell.

During the fighting, a wounded Soviet soldier who she had been taking care of and called himself "Viktor from Voronez" asked her why the city didn't have a strong partisan movement.

[2][3] When she received word that a Gestapo agent nicknamed "the Butcher" would be coming to Kharkiv, she and her partisan unit spent two days planning his capture.

After one put a bag on his head they demanded the names of Nazi collaborators and Gestapo agents before "sentencing" him to death and killing him with a crowbar.

That same day more than one hundred villagers, including herself, were collectively arrested by the Gestapo and told they would be killed by a firing squad if the SS man wasn't found alive soon.
