The Front Range is a mountain range of the Southern Rocky Mountains of North America located in the central portion of the U.S. State of Colorado and southeastern portion of the U.S. State of Wyoming. It is the first mountain range encountered moving west along the 40th parallel north across the Great Plains of North America. The Front Range runs north-south between Casper, Wyoming and Pueblo, Colorado and rises up to more than 9,000 feet above the Great Plains.  Longs Peak, Mount Evans, and Pikes Peak are its most prominent peaks, visible from the Interstate 25 corridor. The area is a popular destination for mountain biking, hiking, climbing, and camping during the warmer months and for skiing and snowboarding during winter. Millions of years ago the present-day Front Range was home to ancient mountain ranges, deserts, beaches, and even oceans.

Die Front Range [] (dt. "Vordere Bergkette") ist eine in Nord-Süd-Richtung verlaufende Bergkette im US-Bundesstaat Colorado.

Le Front Range est une cordillère sur le bord oriental des montagnes Rocheuses aux États-Unis et le long du bord occidental des Grandes plaines. La chaîne s'étend dans l'état du Colorado  dans un axe à peu près nord-sud, non loin de la frontière d'avec le Wyoming. La chaîne comprend les plus haut sommets du bord oriental des Rocheuses, le plus haut pic étant Grays Peak, parmi d'autres pics, tels Torreys Peak, Mont Evans, Longs Peak, Pikes Peak ou Mont Bierstadt.
