The Han (Hankutchin) are an Athapaskan-speaking group who live in the western part of the Yukon Territory in Canada and the east-central part of Alaska in the upper Yukon River drainage area. It has been estimated that there are about thirty-five speakers of the Han language who, along with a few hundred others, are assimilated into White society.
