Charles Edward Swanson (January 3, 1879 – August 22, 1970) served two terms as a Republican U.S. Representative from Iowa's 9th congressional district.

His congressional career ended in the landslide that accompanied the election of Franklin D. Roosevelt to his first term as president.

However, after reapportionment in 1931 placed him in Iowa's 7th congressional district, he prevailed in the Republican primary but lost in the general election to Democrat Otha Wearin.

After resuming the practice of law, Swanson attempted to regain his seat in 1934, but was again defeated by Wearin.

Swanson later served as chairman of the Council Bluffs Board of Tax Review from 1949 to 1968.
