Kuty (Kąty) defence was a skirmish between Polish self-defense units and Ukrainian Insurgent Army unit under commander Ivan Klymshyn (nom de guerre "Crow") and Andriy Melnyk's supporters in the village of Kuty (Polish Kąty) located in Volhynia, Krzemieniec (Kremenets) county, Shumsk commune 3 or 4 May 1943.

After assassinations of individual Poles in late 1942, inhabitants of Kuty formed a self-defense unit.

Since February 1943, when the Massacres of Poles in Volhynia had started, inhabitants who were afraid of attacks, began gathering in the centre of the village at night.

This information leaked out to the villagers who began defence preparations, although many inhabitants did not believe that the UIA was a threat.

In the morning the Germans came from Shumsk, arrived at Kuty concerned by the glow of fire and the sound of gunfire.

Despite the fact that the Polish self-defence forces abandoned the village, they repulsed all attacks by the Ukrainians and thus saved the civilian population.
