The Hupa Indians, named after the Yurok term for their valley, Hupo, are also known by various names such as Cha’parahihu by the Shasta, Hich’hu by the Chimariko, and Kishakevira by the Karok. Their own name, Natinnoh-hoi, refers to their homeland along the Trinity River. The Hupa belonged to the Athapascan linguistic stock and shared close linguistic ties with the Chilula and Whilkut. They primarily resided along the middle course of the Trinity River, especially in the Hupa Valley and on New River. The Hupa established numerous villages, including Aheltah, Cheindekotding, and Haslinding. Historically, their population was estimated at 1,000 in 1770, decreasing to 500 by 1910 and slightly increasing to 575 by 1937. Today, their legacy continues in places like the village named Hupa in Humboldt County.
