John Pitkin Norton (July 19, 1822 – September 5, 1852) was an educator, agricultural chemist, and author.
He then toured continental laboratories, including a visit with countryman Eben Horsford who was in Giessen studying with Liebig.
Norton acted as a foreign correspondent for The Cultivator and American Agriculturalist as he submitted monthly letters describing his observations.
During his short teaching career at Yale (1846–52), he took Samuel William Johnson as a pupil, who would later become one of the country's foremost educators in scientific agriculture.
Norton's house, completed in 1849 and designed by Henry Austin to resemble an Italian villa, was included in the federal government's Historic American Buildings Survey as the John Pitkin Norton House.
