Mostyska Raion ({{langx|uk|Мостиський район}}) was a raion (district) in Lviv Oblast in western Ukraine. Its administrative center was Mostyska. The raion was abolished on 18 July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Lviv Oblast to seven. The area of Mostyska Raion was merged into Yavoriv Raion.{{Cite news|title=Про утворення та ліквідацію районів.
