The Cathedral Range is a mountain range that is part of the Great Dividing Range in Victoria, Australia, located in Cathedral Range State Park. The range is formed from a 7 kilometres (4.3 mi) ridge of upturned sedimentary rock, consisting mainly of sandstone, mudstone and conglomerates of the Devonian Period. This has given the range steep sides, and a narrow razorback ridge. The plateau on the eastern boundary of the park continues to the nearby Lake Mountain cross country ski area.
