Lieutenant General Clarence Ralph Huebner (November 24, 1888 – September 23, 1972) was a highly decorated senior officer of the United States Army who saw distinguished active service during both World War I and World War II. Perhaps his most notable role was as the Commanding General (CG) of the 1st Infantry Division (nicknamed "The Big Red One") during the Normandy landings of World War II.

A farm boy from Bushton, Kansas, who spent almost seven years serving from private to sergeant in the 18th Infantry Regiment, Huebner received a regular commission in November 1916.

During World War I Huebner served on the Western Front and was sent to France with his regiment, the 28th Infantry, which later became part of the 1st Infantry Division ("The Big Red One"), shortly after the American entry into World War I. The division was the first of the American Expeditionary Force (AEF) to be sent overseas during the war. The following year he participated in the first American regimental assault at Cantigny,^[1] through Soissons, Saint-Mihiel, and the Meuse-Argonne. For his service in this war, he received two Distinguished Service Crosses, an Army Distinguished Service Medal, and a Silver Star. He commanded the 2nd Battalion, 28th Infantry at Cantigny after his commanding officer was killed, and later commanded the regiment, one of the youngest regimental commanders in the AEF.

Remaining in the army after the war, Huebner attended the United States Army Command and General Staff School at Fort Leavenworth in 1924 and served on its faculty from 1929 to 1933.

After World War II, Huebner served as Assistant Army Chief of Staff (G-3) at the Pentagon from late 1945 until 1946 when he became Chief of Staff for the United States European Command (EUCOM). He was promoted to lieutenant general on March 28, 1947 and also served as Deputy Commander in Chief of EUCOM from 1947 to 1950. He was the last Military Governor (acting) of the American Zone in Germany from May 15, 1949 to September 1, 1949.

Huebner retired from the army on November 30, 1950.

On September 1, 1951, Huebner became director of New York State's Civil Defense Commission, a post he held until January 1961. A strong advocate of the building of fallout shelters, Huebner believed the United States population would eventually be forced to live full-time in underground shelters and "would see the sunshine only by taking a calculated risk".

Huebner married Florence Barrett in 1921. Following her death in 1966, Huebner married Anna Imelda Mathews in 1968. She died in 1974. All three are buried together in Arlington National Cemetery.^[7]

Huebner was portrayed by Charles Macaulay in the 1980 film The Big Red One, in the opening sequence set in World War I and, in the reconstructed extended version, in 1944 just prior to the Battle of Huertgen Forest.
