Francis Irénée du Pont (December 3, 1873 – March 16, 1942) was an American chemist and executive at the E.I.

He was placed at his father's Carney's Point, New Jersey facility, where he joined in the research into the development of the new smokeless powder.

He was known for his scientific expertise and managerial abilities, became superintendent of Carney's Point, and was the first head of DuPont’s new Experimental Station research facility in 1904.

In 1913, he published, through Saylor Show Print, Wilmington, DE, "Taxation: A Treatise written by F. I. DuPont" developing the ideas of Henry George (1839–1897), the Philadelphia-born author of "Progress and Poverty," which remains the best-selling book ever on political economy.

He calls land speculation "a gross misuse of the power of government" that ought to be abolished by taxation, in order to create prosperity.
