Berestechko (Ukrainian: Берестечко, IPA: [bereˈstɛtʃko] ⓘ) is a town in Lutsk Raion, Volyn Oblast, Ukraine.

Owing to the loss of the Ukrainian Cossacks, the settlement remained under control of the Polish Royal House.

Following the 1917 October Revolution in Russia, violent outbreaks occurred concerning disputes over the boundaries of each empire.

[2][3] The Germans occupied Berestechko (then part of the Reichskommissariat Ukraine) from 23 June 1941 to April 1944, during which they forced all Jews in the town to live in a ghetto, and eventually executed them in 1942.

A witness to the execution in the town stated, "The Jews dug their own pits, accompanied by ten requisitioned Ukrainians.

The Poles would eventually leave the town for other nations, or to be deported off to concentration camps.
