William Liscum Borden (February 6, 1920 – October 8, 1985) was an American lawyer and congressional staffer. As executive director of the United States Congress Joint Committee on Atomic Energy from 1949 to 1953, he became one of the most powerful people advocating for nuclear weapons development in the United States government. Borden is best known for having written a letter accusing physicist J. Robert Oppenheimer of being an agent of the Soviet Union, an accusation that led to the Oppenheimer security hearing of 1954.
