Konrad Oebbeke (2 November 1853, Hildesheim – 1 February 1932) was a German geologist and mineralogist.
He served as privat-docent at the University of Munich, later becoming a professor of mineralogy and geology at Erlangen (1887).
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".
