Guyot Glacier is a long and wide glacier located in the east end of the Robinson Mountains in the U.S. state of Alaska. It begins north of Yaga Peak and heads east-southeast to Icy Bay, south of the Guyot Hills and northwest of Yakutat. It borders Yahtse Glacier on the northeast. The glacier was named by the New York Times expedition of 1886 for Arnold Henry Guyot.
