Vice Admiral Daniel Edward Barbey (23 December 1889 – 11 March 1969) was an officer in the United States Navy who served in World War I and World War II. A graduate of the Naval Academy, he participated in the 1912 United States occupation of Nicaragua and the 1915 United States occupation of Veracruz. While serving with the War Plans Section of the Bureau of Navigation in Washington, D.C. between the World Wars, developed an interest in amphibious warfare. In 1940 he produced "Fleet Training Publication 167 – Landing Operations Doctrine, United States Navy", which would become the Navy's "bible" of amphibious operations, and would remain in use throughout World War II.
