August Adolf Eisenlohr (6 October 1832, Mannheim – 24 February 1902, Heidelberg) was a German Egyptologist.

He studied theology and sciences at the universities of Heidelberg and Göttingen, and spent several years involved in the chemical manufacturing business. In 1862 he introduced a process for producing aniline blue.^[1] In 1865 he resumed his education, taking classes in Egyptian language studies. In 1869 he received his habilitation for Egyptology at Heidelberg and in 1869/70 conducted research in Egypt. In 1885 he became an honorary professor at the University of Heidelberg, where he taught classes in Egyptian archaeology and Semitic languages.^[2][3]

In 1877 he was the first to publish an edition of the Rhind Mathematical Papyrus, considered to be the most important mathematical text discovered in Egypt.^[4]
