The name "Nebraska" is derived from an Oto Indian word meaning "flat water."
Cheyenne County, Nebraska has a rich history that stretches back thousands of years. Before European settlers arrived, the area was predominantly inhabited by Native American tribes, including the Cheyenne, Sioux, and Pawnee. These tribes relied on the fertile land and abundant wildlife for survival, and evidence of their presence can still be found in the form of artifacts and archaeological sites scattered throughout the county.

In the mid-1800s, Cheyenne County experienced a significant influx of settlers as pioneers began to migrate westward in search of new opportunities. The construction of the Union Pacific Railroad in 1867 played a crucial role in the county's development, serving as a vital transportation link and attracting businesses and residents to the area. Initially, the county primarily relied on agriculture, with farmers cultivating crops such as corn, wheat, and oats, as well as raising livestock.

By the late 19th century, Cheyenne County had become a thriving community with various towns and settlements, including Sidney, the county seat. The town served as a hub for trade and commerce, with businesses, schools, and churches being established to support the growing population. Sidney also became an important center for cattle ranching, with the Nebraska Land and Cattle Company operating a large ranch in the area.

Throughout the 20th century, Cheyenne County's economy diversified beyond agriculture, with the exploration and extraction of natural resources such as oil and gas becoming increasingly significant. The county's vast energy reserves attracted companies, which, in turn, brought new jobs and opportunities. Today, Cheyenne County continues to thrive, balancing its rich agricultural heritage with the exploitation of its natural resources, making it a vibrant and dynamic community.
