A home for faith in the Tobacco Valley

Welcome to our parish

Our Lady of Mercy is the Catholic parish of the Tobacco Valley, in the Roman Catholic Diocese of Helena. From our church in Eureka, we serve the communities of the valley and the surrounding country — Eureka, Fortine, Trego, Rexford, and the West Kootenai — here in Montana’s far northwest, just below the Canadian border. All are welcome among us: families who have worshipped here for generations, those newly arrived, seasonal residents, and visitors passing through. Please join us for the celebration of God’s word and the Sacraments.
