Zaruddia (, ) is a village in the Zbarazh urban hromada of the Ternopil Raion of Ternopil Oblast in Ukraine.
The first written mention of the village was in 1564.
In the Second Polish Republic, the town was the seat of the rural commune of Zarudzie until October 1 1933 and then of the rural commune of Koà Âodno in Krzemieniec County, Volhynia Voivodeship. At that time, it was inhabited primarily by Ukrainians, with only a few Polish and Jewish families.
In July 1943, Ukrainian nationalists from the OUN-UPA killed all Polish residents and burned their homes, as a part of Volhynia genocide.
After the liquidation of the Zbarazh Raion on 19 July 2020, the village became part of the Ternopil Raion.
