Lucullus Virgil McWhorter (January 29, 1860 – October 10, 1944) was an American farmer and frontiersman who documented the historical Native American tribes in West Virginia and the modern-day Plateau Native Americans in Washington state. After living in West Virginia and Ohio, in 1903 he moved to the frontier of Yakima, Washington, in the eastern part of the state. He became a rancher and activist, learning much from his Yakama Nation neighbors and becoming an activist for them. In 1914 he was adopted as an honorary member of the Yakama, after helping over several years to defeat a federal bill that would have required them to give up much of their land in order to get any irrigation rights. They named him Hemene Ka-Wan,, meaning Old Wolf.
