Ernest (e) Allard (1820–1900) was a French entomologist who specialised in Coleoptera.
He is not to be confused with the Belgian entomologist Vincent Allard (1921–1994).
Allard's collection was acquired by René Oberthür and is now held by Muséum national d'histoire naturelle, in Paris and Museum Koenig in Bonn.
He was a Member of the Société entomologique de France.
