Tokyo Rose (alternative spelling Tokio 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.

During the war, Tokyo Rose was not any one individual, but rather a group of largely unassociated women working for the same propagandist effort throughout the Japanese Empire. In the years soon after the war, the character "Tokyo Rose" – whom the Federal Bureau of Investigation (FBI) now avers to be "mythical" – became an important symbol of Japanese villainy for the United States. American cartoons, movies, and propaganda videos between 1945 and 1960 tend to portray her as sexualized, manipulative, and deadly to American interests in the South Pacific, particularly by revealing intelligence of American losses in radio broadcasts. Similar accusations concern the propaganda broadcasts of Lord Haw-Haw and Axis Sally, and in 1949 the San Francisco Chronicle described Tokyo Rose as the "Mata Hari of radio".

Tokyo Rose ceased to be merely a symbol during September 1945 when Iva Toguri D'Aquino, a Japanese-American disc jockey for a propagandist radio program, attempted to return to the United States. Toguri was accused of being the "real" Tokyo Rose, arrested, tried, and became the seventh person in U.S. history to be convicted of treason. Toguri was eventually paroled from prison in 1956, but it was more than twenty years later that she received an official presidential pardon for her role in the war.
