Thomas Coleman du Pont (December 11, 1863 – November 11, 1930) was an American engineer and politician, from Greenville, Delaware.

He was President of E. I. du Pont de Nemours and Company, and a member of the Republican Party who served parts of two terms as United States Senator from Delaware.

Du Pont attended preparatory school at Urbana University and earned an engineering degree at the Massachusetts Institute of Technology.

[9] In 1908, du Pont proposed a modern road that was to run the length of Delaware from Selbyville north to Wilmington as part of a philanthropic measure.

Southern Delaware also developed into a major truck farming region due to having much greater access to urban markets.

No longer fully reliant on the railroads to transport their goods, farmers in Sussex and Kent counties could market their fruits, vegetables, and broiler chickens directly to consumers in the north.

On the same day he also lost his bid for the full term to follow, in both instances losing to Democrat Thomas F. Bayard, Jr., a Wilmington lawyer who was married to one of du Pont's cousins.

Senator L. Heisler Ball for the nomination, and going on to defeat Democrat James M. Tunnell, a Georgetown, Delaware lawyer.

In 1927, he introduced a bill proposing the construction of "a coast-to-coast superhighway, five hundred feet wide, as direct as possible from the Atlantic to the Pacific coast".

[17] The later years of his life were marked by his implication in the Teapot Dome scandal, and by lawsuits over various Florida real estate deals.

[citation needed] In 1922, du Pont and his wife donated property on the Chesapeake Bay in Maryland to the Del-Mar-Va Council of the Boy Scouts of America for development of what is now known as Camp Rodney.
