The Rainbow Range, formerly gazetted as the Rainbow Mountains,[3] is a mountain range in British Columbia, Canada, located 40 kilometres (25 mi) northwest of Anahim Lake.

It lies north of the Bella Coola and Atnarko Rivers and south and west of the Dean River, which curves around its north flank, and is relatively drier in climate and easier of terrain than more mountainous areas immediately west.

Once called Tsitsutl, meaning "rainbow mountains" in the Ulkatcho dialect of the Carrier language,[4] that name is now the name of the range's highest peak.

The shield has a diameter of 30 km (19 mi) is now heavily eroded by glaciers carving into the volcanic rock and sands over millions of years.

The Rainbow Range lies partly in the Tweedsmuir South Provincial Park, while to its east the Itcha and Ilgachuz Ranges form the core of the Itcha Ilgachuz Provincial Park.
