Bent's New Fort was a historic fort and trading post along the banks of the Arkansas River in what is now Bent County, Colorado, about nine miles west of Lamar, on the Mountain Route branch of the Santa Fe Trail. William Bent operated a trading post with limited success at the site and in 1860 leased the fort to the United States government, which operated it as a military outpost until 1867. In 1862, it was named Fort Lyon. The fort was abandoned after a flood of the Arkansas River in 1867.

The ruins of the fort and a portion of the Santa Fe Trail were listed as Santa Fe Trail Mountain Route-Bent's New Fort on the U.S. National Register of Historic Places in 2016.
