Saint Kateri Tekakwitha Church (LaGrangeville, New York) is a Roman Catholic parish church located in Lagrangeville, Dutchess County, under the authority of the Roman Catholic Archdiocese of New York.

[2] Donald Swartz was chosen as the architect of the new churches after several design proposals were considered in 2002.

The tabernacle is from Our Lady of Vilnius in Manhattan, and the stained-glass windows by the prominent Bavarian firm of Mayers of Munich (stained glass makers to the Holy See) were transferred from the Harlem Church of St. Thomas the Apostle in Harlem, New York, (1907) installed in 2007.

[4] Both closed churches faced lengthy preservation debates to forestall their demolition and architectural details dispersal.

The former church was transformed into a Faith Formation Center in 2008 and a Parish Office wing was added along with the construction of a new Priest's Residence.
