The Overland Trail was a stagecoach and wagon trail in the American West during the 19th century. While portions of the route had been used by explorers and trappers since the 1820s, the Overland Trail was most heavily used in the 1860s as a route alternative to the Oregon, California, and Mormon trails through central Wyoming. The Overland Trail was famously used by the Overland Stage Company owned by Ben Holladay to run mail and passengers to Salt Lake City, Utah, via stagecoaches in the early 1860s. Starting from Atchison, Kansas, the trail descended into Colorado before looping back up to southern Wyoming and rejoining the Oregon Trail at Fort Bridger. The stage line operated until 1869 when the completion of the First transcontinental railroad eliminated the need for mail service via stagecoach.

Benjamin Holladay was an American transportation businessman responsible for creating the Overland Stage to California during the height of the 1849 California Gold Rush. He created a stagecoach empire and is known in history as the "Stagecoach King".
