Stewart Hall Holbrook (1893 – 1964) was an American logger, writer, and popular historian. His writings focused on what he called the "Far Corner": Washington, Oregon, and Idaho. A self-proclaimed "low-brow" historian, his topics included Ethan Allen, the railroads, the timber industry, the Wobblies, and eccentrics of the Pacific Northwest.
He wrote for The Oregonian for over thirty years, and authored dozens of books. He also produced a number of satirical paintings under the pseudonym of "Mr. Otis," in a style he called "primitive modern." In the early 1960s, he founded the fictitious, tongue-in-cheek James G. Blaine Society, whose goal was to discourage people from moving to Oregon.
