Ernst Ludwig von Leutsch (August 16, 1808 – July 28, 1887) was a German classical philologist born in Frankfurt am Main.
He studied classical philology at the University of Göttingen, where he had as instructors Georg Ludolf Dissen, Christoph Wilhelm Mitscherlich and Karl Otfried Müller.
In 1830 he received his doctorate, and moved to Berlin for a year, where he continued his education under August Boeckh.
Following the death of Schneidewin in 1856, Leutsch took over editorship of the Philologus, a journal on classical studies.
Not a prolific author of books, Leutsch's focus was primarily on his academic teaching, with his favorite subjects being Pindar, Aristophanes, Thucydides, Livy and Tacitus.
