'Geheimrat Dr. Oldenburg' is a German apple cultivar. It was created in 1897 at the Höheren Lehranstalt für Obstbau of Geisenheim in the Rheingau, in Hesse in central Germany.[1] It may also be known as 'Geheimrat Doktor Oldenburg', 'Geheimrat Oldenburg', or simply 'Oldenburg'. It is a quite different apple from the older Russian cultivar 'Duchess of Oldenburg', also sometimes known simply as 'Oldenburg'.
