The Shasta Costa (also known as the Chasta Costa, Shastacosta, Chastacosta, Shastao-Skoton, Shista-Kkhwusta or Shistakwasta ), are a Native American tribe, one of Lower Rogue River Athabascan tribes from southwestern Oregon, who originally lived on the Rogue River and its tributaries, or, more precisely, on the "Lower Illinois River and the Rogue River between present-day Agness and Foster Bar." They spoke Shasta Costa dialect of Tututni (also known as Lower Rogue River Athabaskan) language. They were classified as Rogue River Indians for the purposes of treaty negotiation. One of their villages, Tlegetlinten, was located near Agness, and was eventually "occupied by Euro-American settlers."
