Iva Ikuko Toguri D'Aquino was an American disc jockey and radio personality who participated in English-language radio broadcasts transmitted by Radio Tokyo to Allied troops in the South Pacific during World War II on the Zero Hour radio show. Toguri called herself "Orphan Ann", but she quickly became inaccurately identified with the name "Tokyo Rose", coined by Allied soldiers and which predated her broadcasts.

Tokyo Rose was a name given by Allied troops in the South Pacific during World War II to all female English-speaking radio broadcasters of Japanese propaganda. The programs were broadcast in the South Pacific and North America to demoralize Allied forces abroad and their families at home by emphasizing troops' wartime difficulties and military losses. Several female broadcasters operated using different aliases and in different cities throughout the territories occupied by the Japanese Empire, including Tokyo, Manila, and Shanghai. The name "Tokyo Rose" was never actually used by any Japanese broadcaster, but it first appeared in U.S. newspapers in the context of these radio programs during 1943.
