The Light Infantry Division was a large unit of the Continental Army that fought in the American Revolutionary War. It was formed by unifying the detached light infantry companies from several infantry regiments in September 1781. Its two brigades were made up of three battalions each, though the second brigade was later reorganized into four. The light infantry were regarded as the elite troops of the army. As such they participated in an important assault during the Siege of Yorktown in October 1781.
