Charles H. Utter (Colorado Charlie) (around 1838, near Niagara Falls, New York – after 1912) was an early figure in the American Wild West, best known as a great friend and companion of Wild Bill Hickok. He was also acquainted with Calamity Jane.

In Cheyenne, Wyoming, Wild Bill Hickok became partners with Utter in the train, and in Fort Laramie, Wyoming, Calamity Jane also joined up. The train arrived in Deadwood in July, 1876, and Utter began a lucrative express delivery service to Cheyenne, charging 25 cents to deliver a letter and often carrying as many as 2,000 letters per 48-hour trip.
