Witten (German: [ˈvɪtn̩] ⓘ) is a city with almost 100,000 inhabitants in the Ennepe-Ruhr-Kreis (district) in North Rhine-Westphalia, Germany.

Every district has its own district-number: Witten was first mentioned in historic sources in 1214, however the borough Herbede (which was incorporated into the city in 1975) dates back to 851.

1975 was also the year Witten was first counted to have more than 100,000 inhabitants, the threshold to be considered a large city ("Großstadt") in Germany.

The most recent city council election was held on 13 September 2020, and the results were as follows: In the Landtag of North Rhine-Westphalia, Witten is part of the Ennepe-Ruhr-Kreis II constituency.

Verena Schäffer of the Greens also ran in the constituency and was elected to the Landtag on her party's state list.

Local service is carried out by the BOGESTRA, a joint venture between the cities of Bochum and Gelsenkirchen, to which most of the bus lines in Witten belong.

The coat of arms of Witten with its two lions once belong to the Everhards von Witten-Steinhausen and was first mentioned in 1283.

Because of its long history this coat of arms was the only one in the Ruhr area, that was not forbidden by the Allies in May 1945, after the end of the Second World War.

There are four mosques in Witten, Annen and Herbede today, founded by immigrants from Turkey who arrived in the 1970s and 1980s.
