Ernst Julius Remak (26 May 1849, Berlin – 24 May 1911, Wiesbaden) was a German neurologist who was the son of famed neurologist Robert Remak (1815-1865) and the father of the mathematician Robert Remak (1888-1942). With Edward Flatau (1868-1932), he published an important work on neuritis and polyneuritis that was selected by Carl Nothnagel (1841-1905) to be part of his Handbuch der speziellen Pathologie und Therapie.
