Church of Saint John of Nepomuk, Baroque church building in Nepomuk, Czech Republic.

The Church of Saint John of Nepomuk is a Baroque pilgrimage church in Nepomuk with a twin-tower facade topped by cupola-like helmets, not a dome. Its elongated body under a mansard hipped roof has a cross-shaped central bay and a choir bay with galleries, with curved wall sections between the choir and transept arms.

A first church dedicated to John the Baptist was built between 1643 and 1660 on the reputed site of John of Nepomuk's birth house. After John was canonized in 1729, Count Adolf Bernard of Martinitz had it demolished in 1734 and commissioned Kilián Ignaz Dientzenhofer to build the present pilgrimage church, consecrated in 1737.

The church is dedicated to Saint John of Nepomuk, whose veneration runs deep in this region. Visitors can observe devotional spaces and imagery that local people still visit and respect today.

The church is generally open to visitors during daytime hours, though times may vary by season. It is wise to check locally before visiting and to be respectful with photography, as this remains an active place of worship.

The church has no dome: the two facade towers end in dome-like helmets, and these cupolas, destroyed in the 1835 fire, were rebuilt only in 1878–1879 by architects Antonín Baum and Friedrich Münzberger. The nave is covered by a mansard hipped roof.
