The Lassik belonged to the Athapascan linguistic family and were connected very closely with the Nongatl, who lay just to the north.
Lassik Indians. The name derived from that of a chief.
Location. On a stretch of Eel River, from a few miles above the mouth of the South Fork not quite to Kekawaka Creek; also Dobbins Creek, an eastern affluent of the main stream, and Soldier Basin at the head of the North Fork; to the east they extended to the head of Mad River.
Population. Kroeber (1925) estimates that in 1770, along with the Nongatl and Sinkyone, the Lassik numbered 2,000, and in 1910, 100. (See Alliklik.)
