The 325th Infantry Division is a division of the People's Army of Vietnam (PAVN), first formed in March 1951 from independent units of Bình - Trị - Thiên. It was one of the six original regular divisions of the Viet Minh.

First Indochina War The 325th Infantry Division was first formed in March 1951 from independent regiments (18th, 95th, and 101st) of Bình - Trị - Thiên. It is likely that it only became fully operational in mid-1952. The division first commander cum commissar was Colonel Trần Quý Hai. It was one of the six original regular divisions of the Viet Minh. 

In December 1953 the 325th took part in the Viet Minh probe into Laos.

In late December 1953 seven battalions from Regiment 101 of the 325th and Regiment 66 of the 304th Division moving from Vinh attacked isolated French outposts in the Annamite Range in Annam and Central Laos.

Vietnam War In early 1961 the Division was sent to Laos to support Pathet Lao forces and on 11 April captured Tchepone. This secured an essential area for the expansion of the Ho Chi Minh Trail.

In March 1964 the division was split into the 325A Division which was to begin preparations for moving to South Vietnam, while the 325B Division would rebuild in the North.

The Division's 95th Regiment arrived in Kon Tum Province in December 1964. In February 1965 the 95th was joined by the 101st Regiment. Coming along with the 101st (aka 101A) Regiment was the division commander - Sen. Col. Nguyễn Hữu An. A few months later, the third regiment - the 18th (aka 18A) also arrived but the division was actually dissolved: Col. An was appointed Deputy commander of the Central highlands Front (B3 Front), the 101A stayed in B3 Front while the 18A and the 95A moved to the 5th Military Region's lowlands (B1 Front).

In late 1965, following the Battle of Dak Sut, the 101A Regiment moved south to B2 Front; the 101B Regiment was deployed to B3 Front as a replacement unit and redesignated as the 33rd Regiment, subsequently taking part in the Siege of Plei Me and the Battle of Ia Drang.

In early March 1966, the 95B Regiment under the division deputy commander attacked the A Shau Special Forces Camp of the US 5th Special Forces Group and the ARVN Special Forces, sufferring ~800 killed for allies ~300 killed.

U.S intelligence indicated that the 325C Division was operating in the Vietnamese Demilitarized Zone by July 1967. In its December 1967 PAVN order of battle, III MAF identified elements of three regiments of the 324B Division — the 812th, the 803rd, and 90th — and two of the regiments of the 325C Division — the 29th (18C) and 95C operating south of the Demilitarized Zone.

In 20 January 1968, a PAVN rallier provided US intelligence officers detailed information concerning the 325C Division's plan for the attack and reduction of the Khe Sanh Combat Base before Tet. The 5th and 6th Battalions of the 95C Regiment was to capture Hill 1015 and Hill 861 respectively. The 4/95C Battalion had orders to coordinate with the 101D Regimen to attack the airstrip.
