Solingen (German pronunciation: [ˈzoːlɪŋən] ; Limburgish: Solich) is a city in North Rhine-Westphalia, Germany, 25 km east of Düsseldorf along the northern edge of the Bergisches Land, south of the Ruhr. After Wuppertal, it is the second-largest city in the Bergisches Land, and a member of the regional authority of the Rhineland.

Solingen is called the "City of Blades", and has long been renowned for the manufacturing of fine swords, knives, scissors and razors made by firms such as WKC, DOVO, Wüsthof, Zwilling J. A. Henckels, Böker, Güde, Hubertus, Diefenthal, Puma, Clauberg/Klauberg, Eickhorn, Linder, Carl Schmidt Sohn, Dreiturm, Herder, Martor Safety Knives, Wolfertz, Ralf Aust and numerous other manufacturers.

The medieval swordsmiths of Solingen designed the town's coat of arms. In the late 17th century, a group of swordsmiths from Solingen broke their guild oaths by taking their sword-making secrets with them to Shotley Bridge, County Durham, in England.

Solingen lies southwest of Wuppertal in the Bergisches Land. The city has an area of 89.45 square kilometres (34.54 sq mi), of which roughly 50% is used for agriculture, horticulture, or forestry. The city's border is 62 kilometres (39 mi) long, and the city's dimensions are 15.6 kilometres (9.7 mi) east to west and 11.7 kilometres (7.3 mi) north to south. The Wupper river, a right tributary of the Rhine, flows through the city for 26 kilometres (16 mi). The city's highest point at 276 metres (906 ft) is in the northern borough of Gräfrath at the Light Tower, previously the water tower, and the lowest point at 53 metres (174 ft) is in the southwest.

The following cities and communities share a border with Solingen, starting in the northeast and going clockwise around the city:

• Wuppertal (unitary urban district)

• Wermelskirchen (within the Rheinisch-Bergischer district)
• Leichlingen (Rheinisch-Bergischer district)
• Langenfeld (within the district of Mettmann)

Solingen currently consists of five Stadtbezirke, or boroughs. Each borough has a municipal council of either 13 or 15 representatives (Bezirksvertreter) elected every five years by the borough's population. The municipal councils are responsible for many of the boroughs' important administrative affairs.

The five city boroughs:

• Gräfrath
• Wald (Solingen)
• (Solingen-)Mitte
• Ohligs/Aufderhöhe/Merscheid
• Höhscheid/Burg

Solingen was first mentioned in 1067 by a chronicler who called the area "Solonchon". Early variations of the name included "Solengen", "Solungen", and "Soleggen", although the modern name seems to have been in use since the late 14th and early 15th centuries.

Blacksmiths' smelters, dating back over 2000 years, have been found around the town, adding to Solingen's fame as a Northern Europe blacksmith centre. Swords from Solingen have turned up in places such as the Anglo-Saxon kingdoms in the British Isles. Northern Europe prized the quality of Solingen's manufactured weaponry, and they were traded across the European continent. Solingen today remains the knife-centre of Germany.

It was a tiny village for centuries, but became a fortified town in the 15th century.

After being ravaged by the plague with about 1,800 deaths in 1614–1619, Solingen was heavily fought over during the Thirty Years' War, repeatedly attacked and plundered, and the Burg Castle was destroyed.

Early in the 20th century, Ohligs's chief manufactures were cutlery and hardware, and there were iron-foundries and flour mills. Other industries were brewing, dyeing, weaving and brick-making. In 1929, Ohligs located in the Prussian Rhine Province, 17 miles (27 km) by rail north of Cologne became part of Solingen.

In World War II, the Old Town was completely destroyed by a bombing raid by the RAF in 1944; 1,800 people died and over 1,500 people were injured. As such, there are few pre-war sites in the centre.

From 1945 to 1949 Solingen was part of the British occupation zone. Reconstruction of the old town began in 1949. The newly built Protestant church in Fronhof was consecrated in 1954, and the destroyed towers of the Catholic church of St. Clemens were rebuilt in a different style. By the end of the 1970s, the city's population had increased due to numerous new housing developments in all parts of the city. The city's infrastructure continued to grow, with the opening of the theatre and concert hall in 1963 and the construction of the Viehbachtalstraße motorway through the city in the late 1970s. In 1975, the city grew again with the incorporation of the previously independent town of Burg an der Wupper. In 1993, Solingen made international headlines for a right-wing extremist arson attack in which five Turkish girls and women were killed. The attack was followed by demonstrations and riots in the city.

Since the beginning of the new millennium, the Klingenstadt has undergone a massive transformation as a result of urban development projects such as Regionale 2006 and City 2013. For example, the new Korkenzieherstrasse cycle path was created and the demolition of the Turmhotel and the former Karstadt Passage made it possible to build a new shopping centre on Neumarkt in Solingen-Mitte. After the closure of the old central station in Solingen-Mitte, Ohligs station was officially named the new Solingen central station by Deutsche Bahn AG on 10 December 2006.

On 23 August 2024, a mass stabbing occurred during a festival for the city's 650th founding anniversary.

Solingen's population doubled between the years 1880 and 1890 due to the incorporation of the town of Dorp into Solingen in 1889, at which time the population reached 36,000. The population again received a large boost on 1 August 1929 through the incorporation of Ohligs, Wald, Höhscheid, and Gräfrath into the city limits. This brought the population above the 100,000 mark, which gave Solingen the distinction of being a "large city" (Großstadt). The number of inhabitants peaked in 1971 with 177,899 residents, and the 2006 population figure was 163,263.

The following chart shows the population figures within Solingen's city limits at the respective points in time. The figures are derived from census estimates or numbers provided by statistical offices or city agencies, with the exception of figures preceding 1843, which were gathered using inconsistent recording techniques.

30.9% of the population of Solingen has foreign roots (statistics 2012).

The people of Solingen have been able to elect a council and a mayor since 1374, the year the town was granted its charter. The mayor changed annually on 24 June. Solingen has had a mayor since 1896. During the Nazi era (1933–1945), the mayor was appointed by the NSDAP and not democratically elected by the people of Solingen.

After the Second World War, the military government of the British occupation zone appointed a Lord Mayor. From 1946, the Solingen City Council elected an honorary Lord Mayor and a full-time Lord Mayor from among its members. Until 1997, the honorary lord mayors had mainly representative functions, while the full-time lord mayors were the chief administrative officers of the city of Solingen. In 1997, the dual leadership of the city administration was abolished. Since then there has been only one full-time Lord Mayor. He is the chairman of the council, the head of the city administration and the first representative of the city. Since 1999, the Lord Mayor has been directly elected by the electorate in a secret ballot.

The current mayor of Solingen is Tim Kurzbach of the Social Democratic Party (SPD), elected in 2015 and re-elected in 2020. The most recent mayoral election was held on 13 September 2020, and the results were as follows:

Solingen has a trolleybus network, one of only three in Germany remaining besides Eberswalde and Esslingen am Neckar.

The nearest airports are Düsseldorf Airport and Cologne Bonn Airport. Both airports can be reached by train from Solingen-Hauptbahnhof (change trains at Köln Messe/Deutz station for the S-Bahn 13 to Cologne Bonn Airport). Other easily reached airports are Frankfurt Airport (ICE train stop), Dortmund Airport (railway station "Holzwickede" on the RE7 trainline) and the low cost Weeze Airport (coaches from Düsseldorf Hauptbahnhof).

Solingen has belonged from its beginnings to the Roman Catholic Archdiocese of Cologne (Erzbistum Köln), and more specifically to the Archdeaconry of the Probst (provost) of St. Kunibert, the deanery of Deutz. For reasons that are unclear, the city has long been associated with St. Clement, the third Pope, symbols of whose martyrdom appear on the city’s shield. Although the Protestant Reformation gradually made gains in the city, which was under the control of the Counts of Berg, the population by and large remained Roman Catholic for a while. The Catholic community was newly endowed by the local lord in 1658 and in 1701 received a new church building. In 1827 Solingen became the seat of its own deanery within the newly defined Archdiocese of Cologne, to which the city's current parishes still belong.

As mentioned, the Reformation only gradually gained a foothold in Solingen. A reformed church affiliated with the Bergisch synod was established in 1590, and the city's parish church became reformed in 1649. Lutherans had been present in Solingen since the beginning of the 17th century, and a Lutheran congregation was founded in 1635. In 1672 a formalized religious agreement was reached between the city's religious groups. The Reformation was also introduced in Gräfrath in 1590, where a church council was apparently established in 1629. The Reformed and Lutheran churches were formed into a united church community in 1838 following the general merger of Reformed and Lutheran churches in Prussia in 1817.

The Protestant parishes originally belonged to the district synod of Lennep, today part of the city Remscheid. A new synod was established in Solingen in 1843, and the city acquired its own superintendent, a form of church administrator. This formed the basis for the present-day Church District of Solingen, a member of the Evangelical Church in the Rhineland. With the exception of the free churches, most Protestant churches belong to the Church District of Solingen.

Today approximately 34% of Solingen's population belongs to Protestant churches, and roughly 26% belong to Catholic churches. Other church communities in Solingen include Greek Orthodox, Evangelical Free (including Baptist and Brethren), Methodist, Seventh-day Adventist, Pentecostal, Salvation Army, and free churches. The Church of Jesus Christ of Latter-day Saints, Jehovah's Witnesses and the New Apostolic Church also have communities in Solingen.
