The 25th Marine Regiment (25th Marines) is one of two infantry regiments in the 4th Marine Division of the United States Marine Corps. From its headquarters in Fort Devens, Massachusetts, the regiment commands fifteen training centers in nine states throughout the Northeast. These units consist of approximately 3,500 reserve and active duty Marines and are located from Maine to Delaware, West Virginia and as far west as Ohio. The 25th Marines is primarily a cold weather regiment and frequently trains in northern Norway.

Prepare for employment as a regiment tasked to plan and conduct combat operations in order to locate, close with, and destroy the enemy by fire and maneuver, or to repel his assault by close combat.

The reserve mission is to provide trained and qualified units and individuals to augment, reinforce, or reconstitute the active component of the Marine Corps in time of war, national emergency, and such other times as the national security may require.

The regiment comprises three infantry battalions and a headquarters company:

The 25th Marines was activated on 1 May 1943, at Marine Corps Base Camp Lejeune, North Carolina and was initially manned by Marines from throughout the Northeast. The regiment was subsequently assigned to the 4th Marine Division for service in World War II. Initially located at Marine Corps Base Camp Pendleton, California, the regiment was ordered to the Pacific Theater in January 1944 and participated in the Battle of Kwajalein, Saipan, Battle of Tinian and the Battle of Iwo Jima.
