Rudolf Duala Manga Bell (1873 – 8 August 1914) was a Duala king and resistance leader in the German colony of Kamerun (Cameroon). After being educated in both Kamerun and Europe, he succeeded his father Manga Ndumbe Bell on 2 September 1908, styling himself after European rulers, and generally supporting the colonial German authorities. He was quite wealthy and educated, although his father left him a substantial debt.
