The Chilean Coast Range (Spanish: Cordillera de la Costa) is a mountain range that runs southward parallel with the Andean Mountains, from the morro de Arica to the Taitao Peninsula where it ends together with the Nazca Plate. It is often considered an older range in the Andes orogeny. The highest peak of the range is the Sierra Vicuña Mackenna reaching up to 3000 m. Even if its origin is unknown, it is well accepted between geologists that it is older than than the Andes as such forms the first section of the Andean Orogony. The Chilean Coast Range does not show any sign of volcanic activity.

The range can be divided in several minor ranges. Some of these ranges are:

• Nahuelbuta Range
