Lord Haw-Haw was the nickname for announcer William Joyce of the English-language radio propaganda program broadcast from Germany, it was a familiar sound over the airwaves introducing threats and misinformation during World War II. Called "Germany calling, Germany calling," this was broadcast from Germany to listeners primarily in Great Britain, Ireland and the United States.

William Joyce was originally an American citizen and lived in Britain before taking German citizenship in 1940.
At least three people acted as "Lord Haw-Haw":
Wolf Mittler, a German with a British upbringing who spoke the caricature of an upper-class British accent.
Norman Baillie-Stewart was English and a former officer. He betrayed secrets to the Germans and was sentenced to five years in prison after the war.
William Joyce is most often associated with the name Lord Haw-Haw. He was born in the United States in 1906; his parents were from Ireland.
