Calvin Lewellyn "Cal" Rampton (November 6, 1913 – September 16, 2007) was an American attorney and politician who served as the 11th governor of Utah from 1965 to 1977.

Following his graduation from Davis High School in 1931, Rampton took over his family's automobile business, due to his father's death that same year.

Rampton served in Europe during World War II as Chief of the Army Claims Commission in Paris; he attained the rank of major and received the Bronze Star Medal.

During his governorship, he successfully advocated for increased education spending, civil rights legislation, and allocating federal funds for urban renewal.

He was a supporter of the Equal Rights Amendment to the U.S. Constitution, and advocated successfully for state construction projects, including Salt Lake City’s Symphony Hall (now Abravanel Hall) and the Salt Lake Arts Center (now Utah Museum of Contemporary Art).
