Georg Hieronymus Roderich Stintzing (12 February 1854 – 5 April 1933) was a German internist born in Heidelberg.
Stintzing studied medicine at the Universities of Bonn, Leipzig and Tübingen, receiving his doctorate in 1878 at Bonn. Following graduation he remained in Bonn as an assistant in the institute of physiology of Eduard Pflüger (1829-1910). Later he was an assistant to Hugo von Ziemssen (1829-1902) at the medical clinic in Munich, and in 1890 became an associate professor and director of the medical clinic at the University of Jena.
In 1892 Stintzing attained the title of "full professor" at Jena. One of his better known assistants was internist Ferdinand Gumprecht (1864-1947).
