Demydivka (Ukrainian: Демидівка; Polish: Demidówka) is a rural settlement in Rivne Oblast, Ukraine.

The settlement is located 40 kilometres (25 mi) from the railway station on the Dubno-Krasne-Zdolbuniv line.

[citation needed] In the village of Lishnya, which is located two kilometers from Demydivka, traces of the ancient ruins of the castle have been preserved.

[citation needed] At the beginning of 17th century, Demydiv was a small village, which belonged to several landlords.

[citation needed] During the liberation war of 1648–1654, the people of towns and villages along the rivers Styr and Ikva struggled against Polish noblemen oppression.

Farmers in the fields between Demydivka and Berestechko are still finding weapons and personal belongings of the Cossacks.

Each able-bodied person had to cultivate 6 "morgs" (3.5 hectares) of land, that was almost unsuitable for the agricultural use.

Inhabitants of Demydivka did not suffer just from social oppression, in 1870 and 1873, there were two conflagrations, which burned 76 houses.

Most of victims of the conflagrations were forced to leave their houses, seek livelihoods, and start again from nothing.

[citation needed] The Russian 8th Army, under General Aleksei Brusilov, liberated the town on September 10.

According to the Soviet State Extraordinary Commission, in October 1942, 600 Jews were shot and buried in a pit that had been dug before the shooting.

On this day, a new law entered into force which abolished this status, and Demydivka became a rural settlement.
