Dubienka [duˈbʲɛŋka] is a village in Chełm County, Lublin Voivodeship, in eastern Poland, close to the border with Ukraine[1] on the Bug River.

In 1792, a battle between Polish and Russian armies took place nearby.

In May 1942, the Germans reported that there were 2,907 Jews in Dubienka, some of whom had been transported there from neighboring villages.

On 22 May 1942, the Germans conducted an Aktion in which they murdered a number of Jews at the local Jewish cemetery.

On 2 June 1942, local farmers, under German orders, took Jews by horse and wagon to Hrubieszow where they were held for two days with little food and water, then put on freight trains and taken to the Sobibór extermination camp where they were immediately murdered.
