Chief Moses (born Kwiltalahun, later called Sulk-stalk-scosum - "The Sun Chief") (c. 1829 – March 25, 1899) was a Native American chief of the Sinkiuse-Columbia, in what is now Washington state. The territory of his tribe extended approximately from Waterville to White Bluffs, in the Columbia Basin. They were often in the area around Moses Lake. The tribe numbered perhaps a few hundred individuals.
