The Battle for Quang Tri occurred in and around Quảng Trị City (Quảng Trị Province), the northernmost provincial capital of South Vietnam during the Tet Offensive when the Vietcong (VC) and People's Army of Vietnam (PAVN) attacked Army of the Republic of Vietnam (ARVN) and American forces across major cities and towns in South Vietnam in an attempt to force the Saigon government to collapse. This included several attacks across northern I Corps, most importantly at Huế, Da Nang and Quảng Trị City. After being put on the defensive in the city of Quảng Trị, the Allied forces regrouped and forced the PAVN/VC out of the town after a day of fighting.
