Henderson, formerly known as Henderson Island, is an unincorporated community and a U.S. Post Office in Adams County, Colorado, United States. Henderson has the ZIP Code 80640. Portions of the Henderson area have been annexed by Commerce City, Brighton, and Thornton.
In 1859, John D. "Colonel Jack" Henderson built a ranch, trading post, and hotel on Henderson Island in the South Platte River in Arapahoe County, Kansas Territory. Jack Henderson was the former editor and proprietor of the Leavenworth (Kansas Territory) Journal and an outspoken Confederate conservative politician who had been accused of voter fraud in eastern Kansas. Henderson sold meat and provisions to gold seekers on their way up the South Platte River Trail to the gold fields during the Pike's Peak Gold Rush. Henderson Island was the first permanent settlement in the South Platte River Valley between Fort Saint Vrain in the Nebraska Territory and the Cherry Creek Diggings in the Kansas Territory. Jack Henderson eventually returned to eastern Kansas and, despite his pro-slavery views, fought for the Union in the American Civil War.
Henderson is located at(39.921586,-104.868279). Henderson Island is today the site of the Adams County Regional Park and Fairgrounds.
Along with a post office, a few buildings remain of old Henderson along Brighton Road north of 120th Avenue. The Henderson Congregation Church (now Henderson Community Church) which has been in existence for 110 years and at is current location for 107 years, stands as one of the last remaining vestiges of historical Henderson.
