The 414th Regiment is a training regiment of the United States Army Reserve.

It was originally constituted as an Idaho-based Organized Reserve unit, the 414th Infantry, in 1921 during the interwar period. The 414th fought in World War II with the 104th Infantry Division and was inactivated after the end of the war. It was reactivated postwar and moved to Washington state before being reorganized as a training unit in 1959, becoming part of the 104th Division (Training).

The regiment was constituted in the Organized Reserve on 24 June 1921 as the 414th Infantry, part of the Ninth Corps Area's 104th Division, which was later redesignated as the 104th Infantry Division. It was organized on 22 December 1921 with headquarters at Pocatello, Idaho. 1st Battalion was headquartered at Lewiston, 2nd Battalion at Pocatello, and 3rd Battalion at Boise. On 28 January 1930, the entire regiment was relocated to Pocatello. The 414th conducted summer training in most years with the 38th Infantry at Fort Douglas. As an alternate form of summer training, it also trained civilians at infantry Citizens' Military Training Camps at Fort Douglas or Fort Missoula in some years. Its primary ROTC feeder school was the University of Idaho.

After the United States entered World War II, the regiment was ordered into active military service on 15 September 1942 and reorganized at Camp Adair. The regiment served with the 104th in the Northern France Campaign, the Rhineland Campaign, and the Central Europe Campaign. After the end of the war, it was inactivated on 11 December 1945 at Camp San Luis Obispo, California.
