Hoesch (/hɜːrʃ/; German: Hoesch AG; formerly also Eberhard Hoesch & Sons and Hoesch-Werke) was a German steel and mining conglomerate headquartered in Dortmund and several subsidiaries across the Ruhr region and Siegen. Founded in 1871, by Leopold Hoesch, it employed over 30,000 people by 1938 and was among the largest companies in Nazi Germany.

In 1972, the prominent steel producer merged with the Dutch Hoogovens steel company to form Estel. Hoesch was formerly the largest employer in Dortmund. In 1982, the merger with Dutch company Estel was stopped by Detlev Karsten Rohwedder, and Hoesch became again an independent company. In 1991, German competitor Krupp (presently ThyssenKrupp) bought Hoesch and the merger was completed by 1992.
