Brigham Dwaine Madsen (October 21, 1914 – December 24, 2010) was a historian of indigenous peoples of the American West, of the people of Utah and surrounding states, and of Mormonism. He was a professor at the University of Utah. Madsen published six books on the Shoshone-Bannock. In later life, he became a proponent of 19th-century, as opposed to anciently, positioned Book of Mormon studies, with his edition of the previously unpublished, early-20th-century Studies of the Book of Mormon by B. H. Roberts (1857–1933).
