Julius August Ludwig Wegscheider (27 September 1771 – 27 January 1849), was a German Protestant theologian.

Wegscheider was born at Küblingen (now a part of Schöppenstedt, Lower Saxony). He studied theology at the University of Helmstedt, where he was a pupil of Heinrich Philipp Konrad Henke. From 1795 to 1805, he worked as a tutor to the family of a wealthy Hamburg merchant. In 1805 he presented a dissertation titled Graecorum mysteriis religioni non obtrudendis at the University of Göttingen. He then served as a professor of theology at the University of Rinteln (1806–1810), and at the University of Halle from 1810 onwards.^[1]

Wegscheider was a leading figure of dogmatic theological rationalism—for instance, he considered supernatural revelation to be an impossibility.^[2] Because of his rationalist teachings, he, along with his colleague Wilhelm Gesenius, were attacked by followers of Supernaturalism, creating a situation that led to a government investigation (1830).^[3] Ultimately, he retained his office at Halle, but lost his former influence.^[4]
