Alfred William McCune (June 11, 1849–March, 28 1927) was an American railroad builder, mine operator, and politician from the state of Utah. Owner of several retail and construction businesses, he helped build the Montana Central Railway in Montana and a portion of the Utah Southern Railroad in Utah, founded the Utah and Pacific Railroad, and built railways in Peru, among other projects. He also owned many profitable mines in Canada, Montana, Peru, and Utah, including the Payne Mine—which paid the most dividends in the history of British Columbia. Late in life, he co-founded the Cerro de Pasco Investment Company, which became the largest copper investor in South America and the largest American investor in Peru until it was nationalized in 1974. He was one of Utah's first millionaires.
