Dremmen is a former municipality in the district of Heinsberg, North Rhine-Westphalia, Germany. It has been part of the district town of Heinsberg since 1972. It includes the main village Dremmen and the villages Herb and Boverath.

The neighbouring towns are Hülhoven, Grebben in the north-west, Oberbruch in the north, Porselen the east, Randerath in the Southeast and in the South Uetterath.

Dremmen is located at the edge of the Rur Valley. It is hillier than the surrounding areas. Meadows, fields and woods dominate the landscape. In some places, there is sand mining.

The River Rur is the largest river in the district it flows past Heinsberg into Bleckden near Dremmen. The Rur frequently floods as far as Oberbruch. The river Wurm is by the North East side of Dremmen where the industrial area is situated by Hückelhoven. A small watercourse called Geilenkirchen-Rischden today runs underground in its place.

In the Middle Ages, a Mühlengraben (channel for the operation of water mills) was created, at Randerath where the river Wurm branched off. It ran along the edge of the Wurm. Horst, Porselen, Dremmen and Schafhausen spurred numerous watermills in this period. In the city of Heinsberg, it was destroyed during the Second World War (Jan 1945: Operation Blackcock) and wasn't restored after, the channel was instead used to irrigate agricultural land.

The history of the parish of St. Lambertus can be traced back to the 8th century. The former wooden church burned down in the late 9th century. In the 10th to 11th century, a small hall church made of stone was built at the same place. In 1201, the name of the oldest known pastor of Dremmen was written into the records as: "Nykolaus pastor in drumme". The church hall was repeatedly rebuilt and expanded (Gothic choir Attachments, aisles, Gothic brick tower 1515). In 1716, it burned out completely; after 1721 another new church was built. From 1760, the church seemed too small. By the early 19th century, it was dilapidated. In 1834, the nave was demolished but the tower remained standing. A new three-nave section and room in the classical style was built; In 1835, it was inaugurated. The altar and the modern Calvary dates from the year 1981, the large mural in the presbytery dates from 1993. The organ dates back to 1836, it is from the postwar period with two manuals and 24 registers. In the tower there are five bells that have been hanging since 1953 with the hit tones B0 - c '- it' - f '- g'.

Built in 1890, the railway line Heinsberg-Lindern ("Wurm Switchback") also runs past Dremmen. The local station is no longer used.

On January 1, 1969, Dremmen was incorporated into Oberbruch-Dremmen. Since 1 January 1972, Dremmen has belonged to Heinsberg.

In October 2007, The centre of Dremmen was redesigned including the church, Sidewalks were widened, roads were made narrower and road connections were changed. Pedestrian areas were decoratively paved and separated by green spaces and small walls on the roadway. There is outdoor seating; the village is also called Piazza.
