Gustav von Leonhard (12 November 1816 in Munich – 27 December 1878 in Heidelberg) was a German mineralogist and geologist. He was the son of mineralogist Karl Cäsar von Leonhard.

He studied mineralogy and related sciences at the University of Heidelberg, receiving his doctorate in 1840. He continued his education in Berlin, and in 1841 obtained his habilitation at Heidelberg. In 1853 he became an associate professor of mineralogy at the University of Heidelberg.
