The Yoncalla Indians were a small tribe of Oregon, relatives of the
and speakers of a Southern Kalapuyan dialect.
Like many other West Coast Indian tribes, the Yoncalla people were relocated to the
Siletz Reservation and
Grand Ronde Reservation
during the 1800's, where they were merged with other native peoples and their languages rapidly vanished.
Most Yoncalla descendants still live at Grand Ronde and Siletz today. They are also known as the Yonkalla.
