Simon Leo Reinisch or just Leo Reinisch (26 October 1832 in Osterwitz – 24 December 1919 in Maria Lankowitz) was an Austrian linguist, Egyptologist, Africanist and professor at the University of Vienna.

[1][2] In 1854 Reinisch began studying history, philology, Sanskrit, Hebrew, Arabic and Coptic at the University of Vienna.

In 1873, the same university granted him a full professorship in Egyptian antiquity (Ägyptische Altertumskunde), the first chair for Egyptology in Austria.

[2] 16 years after Reinisch's death, the Reinischgasse street in Vienna-Döbling was named after him.
