Who named the state of Oregon?
It is not known who named the state of Oregon. Oregon became a state on February 14, 1859. The Oregon territory was created in 1848.
Oregon City, Oregon was established by Hudson's Bay Company's Dr. John McLoughlin in 1829, before Oregon became a state and was a territory, near the confluence of the Clackamas River with the Willamette to take advantage of the power of Willamette Falls to run a lumber mill. So it is most likely it was Dr. John McLoughlin who named the city when it was established in 1829.
