Named relative to West Twin Glacier, published by Lawrence (1950, p. 195). East and West Twin Glaciers were at one time joined and the resultant feature was reported as "Twin Glacier" by U.S. Coast and Geodetic Survey (USC&GS) in 1895. Subsequent recession of the glacial front has resulted in two separate glaciers.
