Charles Henri Frédéric Dumont de Sainte-Croix (27 April 1758 – 8 January 1830) was a French zoologist.
A lawyer by trade, he was also an enthusiastic amateur ornithologist. Between 1817 and 1818, he described a number of Javanese bird species discovered by Jean Baptiste Leschenault de la Tour; he also contributed articles on ornithology to the Dictionnaire des sciences naturelles, edited and published from 1816–1830 by F. G. Levrault.
Dumont de Sainte-Croix's daughter, Clémence married René-Primevère Lesson, a surgeon and noted French naturalist.
His younger brother, André Dumont was elected to the Convention during the French Revolution.
