Rocky Mountains, racaké diaraniRockies, minangka tatanan pagunungan sing dawa ing pérangan kulon Amérika Lor. Dawané punjul telung èwu mil (4.800 kilomèter) mbentang saka British Columbia, ing Kanada, tekan New Mexico, ing Amérikah Sarékat. Puncak sing paling dhuwur ya iku Gunung Elbert, ing Colorado, kurang luwih 4.401 mèter) ing ndhuwur permukaané laut (dpl) . Gunung Robson, mapan ing keduwuran 3.954 mèter ya iku puncak paling dhuwur ing Canadian Rockies. Sistem Pegunungan Rocky Mountain kalebu ing United States physiographic regio .

Géografi lan Géologi 

Pegunungan Rocky racaké diartèkaké mbentang saka Liard River ing British Columbia, tekan Rio Grande ing New Mexico. Pegunungan iki bisa uga dianggep mbentang saka Alaska utawa Mexico, nanging pagunungan mau luwih dianggep péranganing kabèh American cordillera ketimbang péranganing Rockies.

Pérangan paling enom saka pagunungan Rocky kaangkat nalika jaman pungkasan Cretaceous (140 juta-65 juta taun sing kapungkur), sanadyan sapérangan pagunungan sisih kidul kaangkat ing jaman Precambrian (3.980 juta-600 juta taun sing kapungkur). Kondisi géologiné kapethak saka kompleks watu beku lan watu metamorf; sing paling enom ya iku watu sedimen (mapan ing dawané bates kidul pagunungan Rocky), lan watu vulkanik saka jaman Tersier (65 juta-1.8 yuta taun kapungkur) mapan ing laladan Pegunugan San Juan lan ing sapropirané laladan liyané.
