Johann Friedrich Gottlieb Goldhagen (May 21, 1742 – January 10, 1788) was a professor of medicine and natural history at the University of Halle.
He went to the University of Halle to study medicine in 1760 and attended the lectures of Friedrich Christian Juncker, Philipp Adolph Böhmer and Johann Peter Eberhard.
In 1769, with support from Andreas Elias Büchner, he received a position of extraordinary professorship in medicine.
He enhanced the collections of the university by adding to the natural cabinet of Friedrich Hoffmann (1660–1742), enriching it with paleontological, anatomical, zoological, and mineralogical specimens.
A memorial obelisk was erected in Dieskau castle park by the university chancellor Carl Christoph von Hoffmann.
