Jeremiah Whipple Jenks (1856–1929) was an American economist, educator, and Professor at the Cornell University.
Born at Saint Clair, Michigan. Jenks graduated from the University of Michigan in 1878. He then studied law while teaching at Mount Morris College in Illinois, and was admitted to the Michigan bar in 1881. He later studied in Germany, earning his doctorate from the University of Halle under Johannes Conrad in 1885.
Jenks held professorships at both Cornell University (1891–1912) as member of the President White School of History and Political Science and New York University (1912 onward). Jenks was a member of the U.S. Commission on International Exchange. He was appointed in 1907 a member of the United States Immigration Commission.
Jenks advised the governments of Mexico, Nicaragua, Germany and China on matters of financial policy, visiting Peking in 1904. He was also an active member of the National Civic Federation where in 1908 he helped to draft a bill to amend the Sherman Anti-Trust Act. Although that bill was ultimately unsuccessful, Jenks also sat on the four-man committee headed by John Bates Clark which drafted a preliminary version of the 1914 Clayton Antitrust Act.
