Hiram Martin Chittenden (1858–1917) was a leading historian of the American West, especially the fur trade. A graduate of West Point, he was the Seattle district engineer for the Army Corps of Engineers (April 1906 – September 1908) for whom the Hiram M. Chittenden Locks in Seattle, Washington, were named. He was one of the first three elected Port Commissioners at the Port of Seattle. He also helped found the Pacific Coast Association of Port Authorities (PCAPA), later known as the Association of Pacific Ports (APP) in 1913.
