William Irving Shuman (1882–1958) was an American businessman, banker and political activist during the late 19th and early 20th century.

After two years, the 23-year-old Shuman was elected director becoming one of the youngest banking officials in the United States.

The organization represented Sangamon, Macon, Christian, Shelby, Montgomery, Macoupin and Moultrie counties.

He was also appointed to the State Bankers' Committee on Agricultural and Vocational Education and, two years later, he became assistant U.S. Treasurer on October 13, 1913.

He was given complete control over the downstate Illinois campaign as well as being involved in the primaries in South Dakota and special work in Minnesota, Michigan and Indiana.
