Mülheim, officially Mülheim an der Ruhr (German pronunciation: [ˈmyːlhaɪm ʔan deːɐ̯ ˈʁuːɐ̯] , lit.'Mülheim on the Ruhr'; Low German: Mölm; Kölsch: Müllem) and also described as "City on the River", is a city in North Rhine-Westphalia in western Germany. It is located in the Ruhr Area between Duisburg, Essen, Oberhausen and Ratingen. It is home to many companies, and two Max Planck Institutes.

Mülheim an der Ruhr was granted city rights in 1808, and a century later its population surpassed 100,000, officially making it a major city.
