Lammot du Pont (1831-1884) was a key member of the du Pont in the mid-nineteenth century. His father was Alfred V. du Pont, the eldest son and successor of Eleuthère Irénée du Pont, the founder of the Dupont.

He obtained a chemistry degree from the University of Pennsylvania and entered into the family business.
