The Itcha Range has had at least two forms of names throughout its history. It was originally named the Itcha Mountains as identified in the 1930 BC Gazetteer. This form of name remained official until March 13, 1947 when it was changed to its current form, Itcha Range, as part of an official government policy. Larger mountain ranges throughout British Columbia, such as the Coast Mountains, retained their gazetted names whereas smaller ones, especially ranges of larger groupings, were subjected to renaming. In more casual speech, the Itcha Range is referred to as the Itchas. The name Itcha is indigenous in origin, coming from the local Tsilhqot'in people.
