Wedding (German: der Wedding, pronounced [ˈvɛdɪŋ] ^ⓘ) is a locality in the borough of Mitte, Berlin, Germany. It was a separate borough in the north-western inner city until it was fused with Tiergarten and Mitte in Berlin's 2001 administrative reform. At the same time the eastern half of the former borough of Wedding—on the other side of Reinickendorfer Straße—was separated as the new locality of Gesundbrunnen.

In the 12th century, the manor of the nobleman Rudolf de Weddinge was located on the small Panke River in the immediate vicinity of today's Nettelbeckplatz. The farmstead, which burned down more than once, remained abandoned in the forest until the 18th century. In the mid-18th century, while Gesundbrunnen was being built up as a health resort and spa town, gambling and prostitution moved into Wedding, transforming it into a pleasure district. In 1864, Ernst Christian Friedrich Schering established the Schering pharmaceutical company on Müllerstraße; the company has been a part of Bayer since 2006. A large hospital at the western rim of the locality was built between 1898 and 1906 on the initiative of Rudolf Virchow. The Rotaprint plant was initiated in Wedding in 1904 and became one of the largest employers locally with about 1,000 staff at its height.

The constant migration of country-dwellers into the city at the end of the 19th century converted Wedding into a working-class district. The labourers lived in cramped tenement blocks, many in the Wilhelmine Ring. After World War I, Wedding was known as "Red Wedding" as it was renowned for its militant, largely Communist working class; it was the scene of violent clashes between paramilitary groups such as the KPD's Roter Frontkämpferbund and the Nazi Party's Sturmabteilung in the late 1920s, including the Blutmai riots of 1929 in which the Social Democratic–controlled Berlin Police killed 33 Communists.

After World War II, Wedding and Reinickendorf together made up the French sector of Berlin. The buildings on the north side of Wedding's Bernauer Straße and the street, including sidewalks, were in the French sector, while the buildings along the southern side were in Soviet territory. When the Berlin Wall was being built in August 1961, many who lived in these buildings frantically jumped from their windows before the buildings could be evacuated and their windows bricked up.

Wedding was also the western terminus of one of the first refugee tunnels dug underneath the Berlin Wall. It extended from the basement of an abandoned factory on Schönholzer Straße in the Soviet sector underneath Bernauer Straße to another building in the west. Though marvelously well constructed and kept secret, the tunnel was plagued by water from leaking pipes, and had to be shut down after only a few days of operation.

A section of the wall has been reconstructed near the spot on Bernauer Straße (since 2001 part of the locality of Gesundbrunnen) where the tunnel ended. Two sections of wall run parallel to one another down the street with a "death strip" in the middle. A nearby museum documents the history of the wall.

Today, Wedding is one of the poorest areas of Berlin, with a high unemployment rate (almost 26%). Almost 17% of the population live on social welfare; 27% live below the poverty line. Foreigners make up 30% of the population. Low rental costs accompany the poverty in Wedding. Therefore, like many inexpensive areas in large cities, it is home to a vibrant artists' community. Many galleries have been founded by artists to provide a space for themselves and their peers to showcase their works. The statistics used here are long out of date and need updating.

Wedding has so far not experienced the boom and development of the 1990s in post-reunification Berlin. Unlike many other 19th-century working class districts like Prenzlauer Berg, the original character of Wedding has been mostly preserved. It is still said though to be a place to find the Schnauze mit Herz (big mouth and big heart) of the Berlin working class.
