Prior to 1921, the upper Colorado River above the confluence with the Green River in Utah had assumed various names. Fathers Dominguez and Escalante named it Rio San Rafael in 1776.

The river above the junction with the Gunnison River, however, was known variously as the Bunkara River, the North Fork of the Grand River, the Blue River, and the Grand River. The latter name did not become consistently applied until the 1870s. In 1921, U.S. Representative Edward T. Taylor of Colorado petitioned the Congressional Committee on Interstate and Foreign Commerce to rename the Grand River as the Colorado River.
