Oberhausen (German pronunciation: [ˈoːbɐhaʊzən]) is a city on the river Emscher in the Ruhr Area, Germany, located between Duisburg (c. 12 km) and Essen (c. 13 km). The city hosts the International Short Film Festival Oberhausen and its Gasometer Oberhausen is an anchor point of the European Route of Industrial Heritage. It is also well known for the Centro, which is the biggest shopping mall in Europe. The city's Sea Life Centre was home to Paul the Octopus.
Oberhausen was named for its 1847 railway station which had taken its name from the Castle Oberhausen (German: Schloss Oberhausen). The new borough was formed in 1862 following inflow of people for the local coal mines and steel mills. Awarded town rights in 1874, Oberhausen absorbed several neighbouring boroughs like Alstaden, parts of Styrum and Dümpten in 1910. After becoming a city in 1901, Oberhausen incorporated the towns of Sterkrade and Osterfeld in 1929. The Ruhrchemie AG synthetic oil plant ("Oberhausen-Holten" or "Sterkrade/Holten") was a bombing target of the Oil Campaign of World War II, and the US Forces had reached the plant by April 4, 1945.
Oberhausen was largely focused on mining and steel production until the 1960s. The last coal mine closed in 1992 and the large Thyssen iron and steel mill closed in 1997 (over 50,000 jobs). The Altenberg zinc factory (German: Zinkfabrik Altenberg) closed in 1981, was taken over by the Rheinisches Industriemuseum (English: Rhineland Industry Museum) in 1984, and opened in 1997.

Oberhausen performs chemical processing, mechanical engineering, and education. The "Neue Mitte Oberhausen" (English: New Central Oberhausen) at the former site of the Thyssen mill has light industry.
Oberhausen has 4 city centres, and Alt-Oberhausen, Sterkrade and Osterfeld are common town centres. The new city centre with its mall draws many people from more distant places as it also boasts a larger number of exceptional shops. Much of the city is composed of low- to medium-density residential areas, most of which date from the 1950s-1970s.
