Maxwell Davenport Taylor (26 August 1901 – 19 April 1987) was a senior United States Army officer and diplomat during the Cold War. He served with distinction in World War II, most notably as commander of the 101st Airborne Division, nicknamed "The Screaming Eagles."

After the war, he served as the fifth chairman of the Joint Chiefs of Staff, having been appointed by President John F. Kennedy. Taylor, along with Secretary of Defense Robert McNamara, played a major role during the early days of the Vietnam War in the decision to deploy US combat troops to Vietnam and to escalate the conflict more generally.

Taylor was born in Keytesville, Missouri, the only child of attorney John Earle Maxwell Taylor and Pearle (Davenport) Taylor. He was raised in Kansas City, graduated from Northeast High School, and attended Kansas City Polytechnic Institute. In 1918, he passed competitive examinations for Congressional appointment by William Patterson Borland to either the United States Military Academy or United States Naval Academy and then passed the Military Academy entrance examination. Taylor attended West Point, graduated fourth in the Class of 1922, and was commissioned as a second lieutenant in the U.S. Army Corps of Engineers. He served in Hawaii with the 3rd Engineers from 1923 to 1926.

Taylor transferred to the Field Artillery and, from 1926 to 1927, served with the 10th Field Artillery, receiving promotion to first lieutenant. Having demonstrated a facility for foreign languages, he studied French in Paris and was then assigned to West Point as an instructor in French and Spanish. He graduated from the Field Artillery School in 1933, and he completed the course at the United States Army Command and General Staff College in 1935.

Taylor was promoted to captain in August 1935 and served at the American embassy in Tokyo from 1935 to 1939, including attaché duty in China in 1937. He graduated from the United States Army War College in 1940 and was promoted to major in July 1940.

Taylor served on the War Plans Division staff in 1940 and took part in a defense cooperation mission to Latin American countries. He commanded the 1st Battalion of the 12th Field Artillery Regiment from 1940 to 1941, and then served in the Office of the Secretary of the General Staff until 1942. He received temporary promotions to lieutenant colonel in December 1941, colonel in February 1942, and brigadier general in December 1942.

In July 1942, Taylor became chief of staff of the 82nd Infantry Division, a position he held from July until October, by which time the division had been converted into the 82nd Airborne Division. This was followed in November when he was placed in command of the 82nd Airborne Division Artillery and received a promotion to the temporary rank of brigadier general in December. In this role he took part in combat in Sicily and Italy. In the late summer of 1943, during the planning for the Allied invasion of Italy, Taylor's diplomatic and language skills resulted in his secret mission to Rome to co-ordinate an 82nd air drop with Italian forces. General Dwight D. Eisenhower, then the Supreme Allied Commander in the Mediterranean Theater of Operations, later said that "the risks he ran were greater than I asked any other agent or emissary to take during the war."

Hundreds of miles behind the front lines of battle, Taylor was forced by the rules of engagement to wear his American military uniform to prevent himself, if captured, from being shot as a spy. He met with Marshal Pietro Badoglio, who had recently become Italy's prime minister, and General Giacomo Carboni, head of Servizio Informazioni Militare, the Italian military's intelligence agency. The air drop near Rome to capture the city was called off at the last minute since Taylor realized that German forces were already moving in to cover the intended drop zones. His efforts behind enemy lines got Taylor noticed at the highest levels of the Allied command.
