Church of Our Lady of the Great Croatian Baptismal Covenant in Knin, Catholic church in Knin, Croatia.

The Church of Our Lady of the Great Croatian Baptismal Covenant is a Catholic church in Knin with about 780 square metres of floor area and 1,100 seats, making it the largest church in Croatia. It was consecrated on 4 August 2015 by Šibenik bishop Ante Ivas.

Construction began in 2011 on a former factory site and the building was consecrated in 2015. This development marked an important religious rebuilding moment for the city of Knin.

The church is named for the Great Croatian Baptismal Covenant, a vow proclaimed in 1941 by Croatian bishops at Marija Bistrica. The Franciscan Province of the Most Holy Redeemer, based in Sinj, built it, and the Franciscan friars of Knin serve as its guardians and parish priests. The church was consecrated on 4 August 2015, the feast of Our Lady of the Snows, by Šibenik bishop Ante Ivas.

The church stands in Knin at the coordinates 44.04157, 16.20068, and its 1,100 seats make it the largest church building in Croatia by seating capacity. The nave covers about 780 square metres, so services and large gatherings fit inside without crowding. The building was consecrated on 4 August 2015 by Šibenik bishop Ante Ivas.

The temporary church that preceded this building was blessed on 28 October 2007 inside the DIV factory hall, before construction of the permanent church began on land the city granted to the Franciscan Province of the Most Holy Redeemer in 2008.
