Franz Hartmann (22 November 1838, Donauwörth – 7 August 1912, Kempten im Allgäu) was a German physician, theosophist, occultist, geomancer, astrologer, and author. 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 was at one time a co-worker of Helena Blavatsky at Adyar. In 1896 he founded a German Theosophical Society. He also supported the Guido-von-List-Society (Guido-von-List-Gesellschaft).
According to Theodor Reuss he was one of the original founders of the magical Order that would later be known as Ordo Templi Orientis, along with Reuss and Carl Kellner.
