Rudnyky (, ) is a village in the Mykolaiv urban hromada of the Stryi Raion of Lviv Oblast in Ukraine.
The first written mention of the village was in 1515.
In the Second Polish Republic, until 1934, the village constituted an independent rural municipality (gmina) within the à »ydaczów County of the Stanisà Âawów Voivodeship. As part of the consolidation reform, on August 1, 1934, it was incorporated into the newly established rural Mikoà Âajów nad Dniestrem municipality in the same county and voivodeship.
March 10, 1944, Ukrainian nationalists from the OUN-UPA murdered 3 Poles here as a part of Volhynia genocide. After the war, the village was detached from Poland and incorporated into the Ukrainian Soviet Socialist Republic.
On 19 July 2020, as a result of the administrative-territorial reform and liquidation of the Mykolaiv Raion, the village became part of the Stryi Raion.
In 1885, a brick Saint Michael church was built in the village, modeled after Saint Andrew church in Kyiv.
