St. Laurentius, Gothic Revival parish church in Merzenich, Germany.

St. Laurentius is a brick Gothic Revival hall church in Merzenich, built between 1898 and 1901 to plans by Theodor Roß. Its west end has a four-story bell tower, now capped by a flat roof after the wartime loss of its spire; a transept and a seven-sided choir close the east end. Inside, ribbed vaults span the three aisles.

Built between 1898 and 1901 under architect Theodor Roß, the church replaced a smaller 13th-century structure that had become too small for the expanding community. This construction marked a major expansion of religious infrastructure in the town.

The church houses a 16th-century Antwerp altarpiece that now stands as a side altar next to the 1899 neo-Gothic high altar, joining different periods of artistic tradition in a single sacred space.

The church is located at Lindenstraße 11 in central Merzenich and operates under the Diocese of Aachen. Regular services are held throughout the week, and visitors are welcome to view the interior during these times.

The tower lost its spire to shelling in World War II and was capped with a flat roof afterwards, which is why it now looks so plain. The crossing flèche was destroyed in the same war and never rebuilt. Inside, wall paintings from the 1898–1901 building period were uncovered and restored in 2013 and 2014.
