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.
