The Army's XXIV Corps met much stiffer resistance in the south, and in late April the Marine division was moved south where it relieved the Army's 27th Infantry Division. The division was in heavy fighting on Okinawa until 21 June 1945, when the island was declared secure.

By the summer of 1946 the division was suffering the effects of demobilization and its combat efficiency had dropped below wartime standards; however, its commitments in China remained. As it became increasingly apparent that a complete collapse of truce negotiations among the Chinese factions was apparent, plans were laid for the withdrawal of all Marine units from Hopeh. The last elements of the division finally left China on 1 September 1947.

Beginning in early 1951 the division participated in several UN (UN) offensives in east-central Korea. This was followed by defending against the Chinese spring offensive composed of over 500,000 troops. By June 1951 the 1st Marine Division had pushed northward and secured the terrain around the Punchbowl and then settled into a defensive line 11 miles long.

In mid-March 1952 the 8th Army, to whom the Marines were attached, instituted Operation Mixmaster. The operation was a massive redeployment of UN forces designed to put more South Korean Army units on the Main Line of Resistance (MLR). The 1st Marine Division was reassigned to the far western end of the United Nations line defending a 35-mile line that encompassed the Pyongyang to Seoul corridor. For much of the next year, in what would be termed the "Outpost War", action along this line consisted of small, localized actions because much of the fighting revolved around the holding and retaking of various combat outposts along key pieces of terrain. This changed in March 1953 when the Chinese launched a massive offensive across the U.N. line. The heavy fighting continued until the Armistice took effect on 27 July 1953. During the Korean War the division suffered combat casualties of 4,004 dead and 25,864 wounded.
