Konrad Oebbeke (2 November 1853, Hildesheim – 1 February 1932) was a German geologist and mineralogist.
He studied at the Universities of Heidelberg and Erlangen, obtaining his doctorate at the University of Würzburg in 1877. Afterwards he worked as an assistant to the Geological Survey of Bavaria. He served as privat-docent at the University of Munich, later becoming a professor of mineralogy and geology at Erlangen (1887). From 1895 to 1927 he was a professor at the Technische Hochschule of Munich.
Oebekke is known for his studies of minerals found in Bavaria, in particular those of economic value. In the Fichtel Mountains he drew attention to the presence of well-crystallized minerals (including topaz) on Epprechtstein.[1] He produced several editions of Wolfgang Franz von Kobell's "Tafeln zur Bestimmung der Mineralien" (Tables for the determination of minerals),[2] and with Ernst Weinschenk (1865-1921), he published editions 6 & 7 of Kobell's "Lehrbuch Der Mineralogie". Other written works by Oebbeke include.
