The 162nd Infantry Regiment is a regiment of the Oregon Army National Guard with headquarters in Springfield, Oregon. In January 2006 as part of the Army's transformation towards a modular force, the 1st Battalion, 162nd Infantry Regiment was inactivated. Many members continued to serve with the 2nd Battalion and other units within the 41st Infantry Brigade Combat Team.

The Oregon Army National Guard is a federally mandated and equipped military organization under the civilian direction of the Oregon Military Department, with the Governor of Oregon as its Commander-in-Chief. It responds to state and national emergencies, military conflicts and natural disasters, and conducts search and rescue operations. While the history of the militia dates back to the establishment of the first Oregon militia in 1843, the present Guard was not established until after 1903. The modern Guard includes citizen soldiers, and its motto is "When we are needed, we are there."
