Ostriv (Ukrainian: Острів) is a village (selo) in Zolochiv Raion, Lviv Oblast, in western Ukraine.

Until 18 July 2020, Ostriv belonged to Busk Raion.

In July 2020, the raion was eliminated as part of Ukraine's administrative reform, which brought the number of raions in Lviv Oblast down to seven.

Busk Raion's territory was combined with Zolochiv Raion.
