James Duncan Graham (April 1, 1799 – December 28, 1865) was an early member and founder of the Corps of Topographical Engineers who engaged in many topographical exercises. A topographical engineer, he directed the re-survey of the Mason–Dixon line, and served on the boundary commissions between the United States and Canada and between the United States and Mexico. He also supervised harbor improvements on the Great Lakes, and documented the lunar tide there.
