Friedrich Georg Weitsch (8 August 1758, in Braunschweig – 30 May 1828, in Berlin) was a German painter and etcher.
After studying at the Kunstakademie Düsseldorf with Lambert Krahe, he obtained a position with the lacquerware manufacturer, Stobwasser [de], where his father was a painting instructor.
Upon returning home, he received an invitation from Charles William Ferdinand, Duke of Brunswick, to work as his court painter.
In that capacity, he created numerous portraits of the Duke and his family; both in Braunschweig and at Salzdahlum Castle.
In 1794, he was elected a member of the Prussian Academy of Arts, Berlin, and married Elizabeth Schroeder.
