OKINAGAN, ō′kē̇-nä′gȧn. An important tribe of Salishan stock (q.v.), and formerly the head of a confederacy including also the Colville, Sanpoil, and a number of other cognate tribes. They occupied an extensive territory upon Okinagan and Similkameen rivers in northern Washington and the adjacent part of British Columbia. They were converted by Jesuit missionaries about fifty years ago, and are now civilized and fairly prosperous. They reside upon the Colville reservation in northern Washington, numbering altogether 575, and have been made citizens under the allotment act.
