The Battle of Gurby (Ukr. Бій під Гурбами) – according to the Institute of History of the National Academy of Sciences of Ukraine, the largest battle that took place 21–25 April 1944 near the village of Gurby (Ukr. Гурби) in the south of Zdolbuniv Raion, between the USSR NKVD troops and UPA forces. It ended with breakthrough of Ukrainian fighters from the encirclement. The number of military and civilian casualties is not precisely known.

The battle took place during the transition of UPA units across the Soviet-German front. The defeated German troops were no longer a threat to the UPA units, so the NKVD departments were the greatest danger to the Ukrainian insurgents.
