The 20th Infantry Regiment is a United States Army infantry regiment.
It was organized on 6 June 1862 at Fort Independence, Massachusetts, as the 2nd Battalion of the 11th Infantry, one of the nine "three-battalion" regiments of regulars, each battalion containing eight companies of infantry, in contrast to the original ten regular regiments of infantry, which were organized on the traditional ten-company line.
Following the Civil War, the Army was reorganized by Congress in July 1866, and the 11th was divided into three regiments, each battalion receiving two additional companies and being organized along traditional lines. The 1st Battalion retained the designation of the 11th Infantry, while the 2nd Battalion became the 20th Infantry and the 3rd Battalion the 29th Infantry.
