William Ellery Sweet (January 27, 1869 – May 9, 1942) was an American banker and politician who served as the 23rd governor of Colorado from 1923 to 1925.

Early life and career William was born in Chicago, Illinois, on January 27, 1869, to Channing and Emeroy Sweet. His family moved to Colorado Springs, Colorado, in 1872 when William was two. He attended school there, and graduated from high school in 1887. After high school, he went to college in Philadelphia, Pennsylvania, at Swarthmore College. He graduated from Swarthmore in 1890, after three years attending, and earned his bachelor's degree. He also excelled playing quarterback for the college football team and was a member of Phi Kappa Psi fraternity.

On October 19, 1892, Sweet married Joyeuse L. Fullerton in Philadelphia.

In 1924, after initially supporting McAdoo, he became a "favorite son" candidate for the Colorado delegation at the 1924 Democratic National Convention. In the 1928 presidential election, Sweet crossed party lines to support Herbert Hoover.

Sweet made two unsuccessful attempts to run for the United States Senate as the Democratic nominee in 1926 and for the Democratic nomination in 1936. In the final years of his life, William was a proud supporter of the Progressive Party. He died on May 9, 1942, in his Denver home. He had a Georgian Revival style mansion in what is now the Humboldt Street Historic District.
