Gnadenkirche, Protestant church in Bergisch Gladbach, Germany.

Gnadenkirche is a yellow-plastered Protestant church in Bergisch Gladbach, built as an octagonal central structure on a Dutch model. The rear tower with a curved hood and lantern, and the two-storey parish house connected to it, date from 1788; the former parish house now serves as the community office. In 1899 the central building was extended toward the entrance and given a columned portico.

The Reformed congregation received permission to build in 1775, and the church was erected in 1776 to a design by Johann Georg Leydel as an octagonal central building on a Dutch model. The rear tower with its curved hood and lantern, together with the two-storey parish house, followed in 1788. In 1899 O. March extended the building toward the entrance and added a columned portico. It is listed as monument no. 27 in Bergisch Gladbach.

The church serves as the center of Protestant community life in Bergisch Gladbach, hosting services, concerts, and local gatherings. It remains an important gathering place for the evangelical congregation and visitors.

The church is located at Hauptstraße 256 and is easily accessible on foot or by public transportation. Administrative offices are open during specific times for visitors and community inquiries.

On the disused cemetery beside the church stand grave monuments from the 16th to the 19th century, older than the 1776 church itself. Two stained-glass windows showing the Nativity and the Crucifixion date from around 1400 and were reused in the building.
