Butrimonys (Yiddish: בוטרימאַנץ) is a small town in Alytus County in southern Lithuania.

[1] On 9 September 1941, shortly after the Nazi invasion of the Soviet Union, the Jews of Butrimonys were massacred by Einsatzgruppen and Lithuanian collaborators.

According to the Jäger Report, 740 Jews were murdered in one day: 67 men, 370 women, and 303 children.

[2] What distinguished Butrimonys from hundreds of similar crimes in the Baltic region was the survival of a detailed record left by a local Jew Khone Boyarski.

Boyarski was later killed by the Nazis; the letter was discovered by accident by a graduate student in the archives of Yad Vashem.
