Dr. Elijah White (1806–1879) was a missionary and agent for the United States government in Oregon Country during the mid-19th century. A trained physician from New York State, he first traveled to Oregon as part of the Methodist Mission in the Willamette Valley. He would return to the region after a falling-out with mission leader Jason Lee as the leader of one of the first large wagon trains across the Oregon Trail and as a sub-Indian agent of the federal government. In Oregon he used his authority to regulate affairs between the Natives and settlers, and even between settlers. White would leave the region in 1845 as a messenger for the Provisional Government of Oregon to the United States Congress, returning in 1850 before leaving again for California in the early 1860s.
