Front Range

The Front Range is shown highlighted on a map of the western United States

The Front Range is a mountain range in the United States on the eastern edge of the Rocky Mountains, and on the western edge of the Great Plains. The range is mostly within the state of Colorado, and runs roughly north-south, from near the Wyoming-Colorado border to south-central Colorado. The range contains the largest peaks along the eastern edge of the Rockies. The tallest mountain in the Front Range is Long's Peak.

The name "Front Range" is also applied to the Colorado Front Range, the populated region of Colorado on the plains just east of the range.
