William Brooke Joyce, nicknamed Lord Haw-Haw, was an American-born fascist and Nazi propaganda broadcaster during the Second World War. After moving from New York to Ireland and subsequently to England, Joyce became a member of Oswald Mosley's British Union of Fascists (BUF) from 1932, before finally moving to Germany at the outset of the war where he took German citizenship in 1940.

Lord Haw-Haw was a nickname applied to William Joyce and several other people who broadcast Nazi propaganda to the United Kingdom from Germany during the Second World War. The broadcasts opened with "Germany calling, Germany calling," spoken in an affected upper-class English accent. The same nickname was also applied to some other broadcasters of English-language propaganda from Germany, but it is Joyce with whom the name is overwhelmingly identified.
