Karamba Diaby (born November 27, 1961) is a Senegalese-born German chemist and politician.
Diaby grew up in Marsassoum, Senegal. The youngest of four children, he was raised by his sister after losing both of his parents by the time he was 7. A graduate of the Cheikh Anta Diop University, he left Senegal to study chemistry in East Germany in 1985, and stayed past the reunification of Germany, after which he became more involved in political and social activism.
On September 22, 2013, Diaby was elected to the Bundestag as a Social Democratic Party of Germany candidate from Halle (Saale), Saxony-Anhalt; Diaby became one of the first two Bundestag members of African ancestry, alongside Charles M. Huber (born to a Senegalese father and German mother), who was elected at the same time from the Christian Democratic Union.
