Willis Sweet (January 1, 1856 – July 9, 1925) was the first United States Representative elected from Idaho following statehood in 1890.
Sweet served as a Republican in the House from 1890 to 1895, representing the state at-large.
He vigorously demanded "Free Silver" or the unrestricted coinage of silver into legal tender, in order to pour money into the large silver mining industry in the Mountain West, but he was defeated by supporters of the gold standard.
