7th Marines was formed in Philadelphia, Pennsylvania on 14 August 1917. During World War I, the 7th Marine Regiment immediately deployed to Cuba for two years. They were deactivated in the demobilization that followed the war. When the Marine Corps was once again called upon to provide peacekeepers in the Caribbean (1933), elements of the regiment were reactivated and deployed on Naval ships off the Cuban coast. At the end of the crisis, 7th Marines was once again inactivated.
On 1 January 1941, the 7th Marine Regiment was re-activated at Guantanamo Bay, Cuba. The regiment moved to what is today Marine Corps Base Camp Lejeune, North Carolina. On 18 September 1942 the regiment landed in the Solomon Islands on Guadalcanal. For four long months the regiment relentlessly attacked the Japanese defenders and repulsed banzai charges and suicidal attacks. Medal of Honor recipient "Manila John" Basilone, Mitchell Paige, and Navy Cross recipient Lewis "Chesty" Puller, served in the 7th Marine Regiment in the Guadalcanal Campaign
Arriving in Australia in January 1943, the vast majority of the regiment suffered from malaria, wounds or fatigue.
Again and again the regiment was called upon to storm the Japanese-held islands in the Pacific. The Seventh Marine Regiment fought in such places as Eastern New Guinea, New Britain, "Bloody Peleliu" and the island fortress of Okinawa. 7th Marines saw intense fighting on the island of Okinawa where they sustained 700 Marines killed or wounded in the fighting to take Dakeshi Ridge and another 500 killed or wounded in the fighting near Wana Ridge.
After the surrender of Japan, 7th Marines took part in the Occupation of Northern China from 30 September 1945 through 5 January 1947. They returned to MCB Camp Pendleton, California in January 1947 and were reassigned to the 1st Marine Division. The regiment was deactivated on 6 March 1947 as part of the Marine Corps' draw down of forces after the war. 7th Marines however was quickly reactivated on 1 October 1947 but only as a shell of its former self as it consisted of only four companies. Company "C" deployed to China from 2 May through 23 June 1949 to safeguard the withdrawal of Americans and was the last element of Fleet Marine Force to depart China.
On 17 August 1950, after the outbreak of the Korean War, the Regiment was reactivated, and on 21 September 1950 the Regiment landed at Inchon, as part of the 1st Marine Division. The regiment fought from Inchon to the Yalu, at The "Frozen Chosin" Reservoir and in the long defense of South Korea until the armistice.
In fall of 1962, substantial parts of the regiment embarked for the Caribbean and possible action in Cuba, aimed at forcing the removal of Soviet nuclear missiles pointed at the United States. As the Cuban Missile Crisis subsided, The Seventh Marines returned to Camp Pendleton, California.
In 1965, the regiment was deployed to South Vietnam.

In August 1990, shortly after shifting the home of the regimental colors from Camp Pendelton to the Marine Corps Air Ground Combat Center Twentynine Palms, California, the Marines and sailors of the regiment deployed to Saudi Arabia. They were part of the attack into Kuwait and eventual victory. In August 1991, as a result of the unique organizational changes that occurred in Seventh Marines, and with the addition of 3rd LAR Battalion, 3rd Tank Battalion and Delta Company, 3rd Assault Amphibian Battalion, Seventh Marine Regiment became Regimental Combat Team Seven (RCT-7).
In December 1992, RCT-7 deployed on Operation Restore Hope to relieve famine and return order to Somalia, remaining there for five months.
On 13 August 1993, on the eve of the regiment's 76th anniversary, the regiment formally marked the return to its original designation by changing its name from Regimental Combat Team 7 to 7th Marines (Reinforced).

In January 2003, the 7th Marines deployed to Kuwait as part of Operation Iraqi Freedom. On 21 March, the regiment crossed the line of departure into Iraq as it moved to seize and cut off Iraqi units around Basrah. During the course of the next few weeks, the regiment continued the offensive to capture Baghdad and collapse the regime of Saddam Hussein. During much of the attack north, the regiment led the 1st Marine Division in the deepest attack in Marine Corps history. The regiment again deployed to Iraq in February 2004 where they were based at Al Asad Airbase and were responsible for security and stabilization operations in the western desert regions of Al Anbar Province.
