Franz Hartmann (22 November 1838, Donauwörth – 7 August 1912, Kempten im Allgäu) was a German medical doctor, theosophist, occultist, geomancer, astrologer, and author.

Hartmann was an associate of Helena Blavatsky and was Chairman of the Board of Control of the Theosophical Society Adyar.

[1] His works include several books on esoteric studies and biographies of Jakob Böhme and Paracelsus.

He translated the Bhagavad Gita into German and was the editor of the journal Lotusblüten.

He also joined and supported the far-right esotericist Guido-von-List-Society (Guido-von-List-Gesellschaft) which was a modern Pagan new religious movement which promoted Wotanism, a proposed revival of the religion of the ancient German race, and which included an inner set of openly racist Ariosophical teachings that Guido-Von-List termed Armanism.
