Church of Saint Gall in Chlumec, Roman Catholic church in Chlumec, Czech Republic.

The Church of Saint Gall is a Roman Catholic parish church in the centre of Chlumec, built in 1847–1852 in Romanesque Revival style to designs by J. Katz and A. Smöch. Its rectangular three-aisle hall is vaulted with shallow domes on square pillars, ending in a semicircular presbytery, with a square tower rising from the south facade.

A church existed here by 1359, when priest Niklas z Barau paid 18 kop grošů in papal tithe. In 1590 Petr Kölbl z Geisingu rebuilt it in Baroque style and added a square tower; after damage in the Napoleonic Wars it was rebuilt in Neo-Romanesque style by architects J. Katz and A. Smöch between 1847 and 1852, consecrated on 18 November 1849.

The church is dedicated to Saint Gall, and mass is held on the second and fourth Sunday of each month at 4 pm. A memorial plaque at the tower entrance lists local soldiers killed in World War I, and a sculpture of a wounded soldier, funded by soldiers' mothers and widows and unveiled in 1936, stands below the entrance steps.

The church sits in a central location within Chlumec and is walkable from the town center. Visitors should be aware that regular services take place at specific times, so access may depend on when services are scheduled.

On the north outer wall, eleven Renaissance gravestones of the Kölbl family, owners of the estate in the 16th and 17th centuries, are set into the masonry; they were moved here partly from a vanished cemetery and partly from the demolished Church of St. Lawrence near Český Újezd. Two of the best-preserved stones of the former lords are walled up inside the church on either side of the chancel.
