Kiev-Sviatoshyn Raion (Ukrainian: Києво-Святошинський район) is a raion (district) in Kiev Oblast of Ukraine, adjacent to the city of Kiev, its administrative center. Kiev does not belong to the raion, and vice versa.
Established in 1962, Kiev-Sviatoshyn Raion borders Borodianka Raion and Vyshhorod Raion to the north, Vasylkiv Raion and Obukhiv Raion to the south, Makariv Raion to the west, and with the city of Kiev to the east. The cities of Irpin (since 1962) and (since 2007) Bucha, administratively incorporated as cities of oblast significance, do not belong to the raion, but their areas are enclosed by the raion.
