Georg August Pritzel (2 September 1815, Carolath – 14 June 1874) was a German librarian and botanical writer.
He studied in Breslau, graduating with a dissertation titled Anemonarum revisio. In 1851 he began work as a Hülfsarbeiter at the royal library in Berlin, a post which eventually led to curator duties. From 1855 onwards, he served as archivist at the Prussian Academy of Sciences.
The botanical genus Pritzelago from the family Brassicaceae was named after him by Otto Kuntze (1843-1907).
