Seraing (French pronunciation: [səʁɛ̃] ^ⓘ; Walloon: Serè) is a municipality and city^[2] in Liège Province, Wallonia, Belgium.

The municipality consists of the following districts: Boncelles, Jemeppe-sur-Meuse, Ougrée, and Seraing. With Liège, Herstal, Saint-Nicolas, Ans, and Flémalle, it forms the greater Liège agglomeration (600,000 inhabitants). South of Seraing are the Condroz and the Ardennes regions.^{[citation needed]}

The first mention of Saran dates from 956, when a Carolingian farming domain extending on both sides of the river Meuse and owned by someone named Saran was donated to the abbey of Sint-Truiden. The whole territory soon passed to the Prince-Bishopric of Liège.

ThThe first ironworks were founded there in 1809. John Cockerill and his brother James revolutionized the steel industry by using blast furnaces and coke instead of traditional charcoal. These inventions were the basis for the new company, John Cockerill & Cie established in Seraing in 1817.^{[citation needed]}
