William Denison Lyman (1852–1920) was an American historian and educator of the Pacific Northwest. Born in Oregon to missionary parents who had crossed the plains, he graduated from Williams College and in 1889 joined the faculty of Whitman College in Walla Walla, Washington, where he was professor of history for the rest of his life. He wrote The Columbia River, a history and description of the great river of the region, and histories of Walla Walla County, of Yakima Valley and of old Walla Walla County, as well as many articles on the exploration and settlement of the Northwest.
