Edwin Carl Johnson (January 1 1884 May 30 1970) was a Democratic Party politician from the state of Colorado. He represented his state for three terms in the United States Senate from 1937 to 1955 and served as governor of Colorado from 1933 to 1937 and from 1955 to 1957. He was born in Scandia, Kansas, moved with his family to Nebraska as a child, and started a farm in Colorado as a young man. He was lieutenant governor of Colorado from 1931 to 1933. He died in Denver, Colorado.

He was perhaps best known for making a speech on the Senate floor criticizing the extra-marital affair of actress Ingrid Bergman, who at the time was married to Peter Lindstrom, a physician. Bergman's affair with Italian director Roberto Rossellini became a cause celebre as a result of Johnson's speech, forcing her to escape to Europe for several years until her return in the 1956 blockbuster film Anastasia.
