Dominique Vivant, Baron Denon (4 January 1747 – 27 April 1825) was a French artist, writer, diplomat, author, and archaeologist. Denon was a diplomat for France under Louis XV and Louis XVI. He was appointed as the first Director of the Louvre museum by Napoleon after the Egyptian campaign of 1798–1801, and is commemorated in the Denon Wing of the modern museum and in the Dominique-Vivant Denon Research Center. His two-volume Voyage dans la basse et la haute Egypte ("Journey in Lower and Upper Egypt"), 1802, was foundational for modern Egyptology.

Vivant Denon was born at Chalon-sur-Saône to a family called "de Non", of the "petite noblesse" or gentry, and until the French Revolution signed himself as "le chevalier de Non". Like many of the nobility, he revised his surname at the Revolution to lose the "nobiliary particle" "de". He seems to have consistently avoided using his baptised first name "Dominique", preferring his middle name "Vivant", and so is usually known as "Vivant Denon". He was created "Baron Denon" by Napoleon in August 1812, at the age of 65.
