Edith von Coler (also: Edit Von Coler; née Edith Heinemann, 9 July 1895 — 14 May 1949) was a German propagandist who acted as an agent of influence and unofficial diplomatic conduit in the Kingdom of Romania before and during World War II. Family connections brought Von Coler to the attention of the Nazi Party, leading to the German Foreign Office sending her to Romania. There, she helped to resolve infighting in the German community and helped to negotiate the 1939 German–Romanian Economic Treaty which subjugated Romania to Nazi Germany.
