Baumberg (also Monheim-Baumberg) is part of the city of Monheim am Rhein in the district of Mettmann in North Rhine-Westphalia (Germany) at the southern border of Düsseldorf, placed on the eastern bank of the river Rhine. Baumberg consists of an area of about 6 km, with about 14,000 residents in 2023 (one third of the 43,000 in Monheim am Rhein).

Baumberg was first recorded in 1296 as "Boimberg", a village part of the Earldom of Berg. The tower of the Catholic Church St Dionysius which was built in medieval times is left until today whereas the church has been rebuilt according to blueprints of the architect Bernhard Rotterdam in the 1950s. Until the 20th century Baumberg was a rural village, inhabited by mainly fishermen, (goat-)farmers and traditional craftsmen like basket weavers. The eel smokehouse in Baumberg existed from 1857 to 2009 and used fish from its own catch until water pollution in the Rhine became too severe in the 1960s, and then eels from Northern Europe. At the end of the year 1900 about 1,200 people were living in Baumberg and 98 per cent of them were Catholics. The communities of Monheim and Baumberg joined the goat breeding association of the rural district of Solingen in November 1902. The goat, in colloquial German known as “Hippe”, was the “little man's cow”. The district promoted goat breeding, particularly in the small and poor rural community of Baumberg. A special billy goat station was set up on Schallenstrasse, which existed until 1932. On September 26, 2004, the Boomberger Hippegarde association unveiled a monument on a traffic island at the junction of Schallenstrasse / Im Sträßchen in memory of the former goat breeding station of the Solingen district. The bronze sculpture is industrially manufactured and shows a billy goat standing on its hind legs. In 1908 the Voluntary Fire Department Baumberg was founded. Baumberg belonged to the Prussian Kreis Solingen (English: rural district of Solingen) from the 19th century to 1929. Baumberg belonged to the newly established Kreis Solingen-Lennep in 1929 in which was renamed Rhein-Wupper-Kreis in 1931.

2,000 people lived in Baumberg in 1946 after the end of World War II. In 1951 Baumberg became part of southern neighbouring Monheim in the German state of North Rhine-Westphalia. The Hein Lehmann AG workers' settlement was built between 1952 and 1956. The housing projects by Demag and trade-union-owned building company Neue Heimat boosted population to 5,000 residents in 1965 and to 10,000 in 1969. In 1975, after the municipal reform was carried out, Monheim and Baumberg became districts of Düsseldorf for nearly a year, while the Hitdorf city district of Monheim of became a city district of Leverkusen. On 6 December 1975 the municipal reform resolution against the independence of Monheim and Baumberg was repealed, but Hitdorf remained a district of Leverkusen. The Landtag of North Rhine-Westphalia confirmed this decision by vote on 18 May 1976. On 1 July 1976 Monheim and its city district Baumberg regained their independence and belonged to the district Mettmann (German: Kreis Mettmann). In the eastern part of Baumberg a new quarter with block of flats and terraced houses, the so-called Austrian quarter (German: Österreich-Viertel), was created from the late 1970s to the 1990s.

In 1985, the allotment garden Im Baumberger Feld was created on the border with Düsseldorf-Hellerhof, which has 98 plots.

In 2002, the Knipprather Busch allotment garden association, which was established in 1972, moved to Loheck in Baumberg, because the original location on the former Henkel landfill was to be renovated.

Nowadays Baumberg is mainly a suburban residential area with many commuters to the surrounding towns.

Around a third of Monheim's approximately 43,000 residents, over 14,000 residents, lived in the Baumberg district in 2023.

From 1967 to 1975, the Baumberg Protestant Church Friedenskirche was built, which was made necessary by the large influx of people. In 2020, the Protestant parish in Baumberg had 3,559 members. It belongs to the Evangelical Church of Monheim (9,718 parishioners in 2020), which includes the urban area of Monheim am Rhein and the Hitdorf district of Leverkusen, i.e. the Monheim urban area before the municipal reform in North Rhine-Westphalia in 1975.

In 1908 the first tram ran between Monheim and Langenfeld train station and quickly became the most important means of transport. As a result of motorization after the Second World War, the number of passengers fell drastically; The last tram with the final stop on the Hauptstraße (main street) below the Church of St. Dionysius ran on 15 June 1963.

The citizens' office, which opened once a week at Holzweg 95 from April 18, 2000, was not well received. It was closed on November 9, 2005, as a result of the austerity package passed by the council. From 1 April 2015 all citizen concerns could be addressed at the Monheim Citizens' Office on Wednesdays from 9 a.m. to 12 p.m. It was located in the premises of the Raiffeisenbank which also was given up after a short time due to lack of demand.

In 1981 the district sports facility was set up in the Österreichviertel. It was reopened because of the creation of the new Waldebeerenweg residential area and relocated towards Berghausener Straße.

The costs for an associated sports hall, which was completed at the end of May 2018, amounted to 2.16 million euros.

There are four joint practices for general medicine, three dentists and an ophthalmologist in Baumberg. Until August 31, 2013, there was the St. Josef Hospital in Monheim am Rhein, which was closed due to high losses (8.5 million euros from 2008 to 2013) and demolished in 2017. The health campus, which was completed in 2022, was built there. Currently, the nearest hospitals are in Langenfeld-Richrath (St. Martinus Hospital of the GFO Association) and Düsseldorf-Benrath (Sana Hospital).

The shops are mainly located in the Holzweg shopping center, which was built in 1969 and was rebranded "Holzweg-Passage" in 2020 after renovation. Renovation was continued until 2021. The shops are not very specialized, mainly selling consumer goods and everyday items such as food, flowers and stationery and there is a kiosk with a post office.

Businesses consider the small number of parking spaces to be problematic, particularly on the Hauptstraße. A beautification of the Hauptstraße using city funds was carried out from mid-February 2016 and finished in June 2017. The Foundry, located on Berghausener Straße/Heinrich-Hertz-Straße and operated by Schmolz + Bickenbach, was closed in 2009.
