Robert "Doc" Newell (March 30, 1807 – November 24, 1869), was an American politician and fur trapper in the Oregon Country. He was a frontier doctor in what would become the U.S. state of Oregon. A native of Ohio, he served in the Provisional Government of Oregon and later was a member of the Oregon State Legislature. The Newell House Museum, his reconstructed former home on the French Prairie in Champoeg, is listed on the National Register of Historic Places.
