Kseniya Semyonovna Konstantinova (Russian: Ксения Семёновна Константинова; 18 April 1925 – 1 October 1943) was a medic in the Red Army during World War II who was posthumously awarded the title Hero of the Soviet Union on 4 June 1944.

In 1937 she and her two younger brothers witnessed the NKVD arrest their father, Semyon Grigorievich, a primary school teacher, on charges under article 58 after a false accusation from colleagues.

Desperate to prove herself and wanting to help support the war effort as much as possible, she ran away from home in 1943 to join the army as a medic, leaving a note behind for her mother explaining that she felt compelled to go to the front.

[1][2][3] Not even 18 years old yet, after volunteering for the army in early 1943 she was originally sent to an infantry training brigade in the Volga Military District.

After being taken as a prisoner of war by the Nazis she refused to give any information about the nature of Soviet military operations in the area, for which she was brutally tortured and mutilated before eventually being stabbed and pinned to the ground with a stake.
