Quảng Trị province in the context of Cồn Cỏ special administrative region

Huế, formerly Thừa Thiên Huế province, is the southernmost coastal city in the North Central Coast region, approximately in the center of the country, and an educational, medical, scientific, and cultural hub of Vietnam. It borders Quảng Trị to the north, Đà Nẵng to the south, Salavan and Sekong of Laos to the west and the South China Sea to the east. As one of the country's six direct-controlled municipalities, it falls under the administration of the central government.

Huế has 128 km of coastline, 22,000 ha of lagoons and over 200,000 ha of forest. The city is located in the middle of the North Central and South Central regions (including the South Central Coast and Central Highlands), and is transitional in many aspects: geology, climate, administrative division and local culture.

The Gianh River (vernacular Vietnamese: sông Gianh, also known as Gianh giang; Sino-Vietnamese: Linh Giang 靈江) is a river in the Quảng Bình province of Vietnam's North Central Coast (Bắc Trung Bộ). The river is 268 kilometres (167 mi) in length.

The Gianh–Son River served as the boundary between Đàng Ngoài and Đàng Trong, ruled by rival families, during the partition of Vietnam in the 17th and 18th centuries following the Trịnh–Nguyễn War. The 17th parallel, used as the border between North Vietnam and South Vietnam from 1954 to 1975, was located just south of the Gianh River, at the Bến Hải River in Quảng Trị province.

Quảng Bình was formerly a southern coastal province in the North Central Coast region, the Central of Vietnam. It borders Hà Tĩnh to the north, Quảng Trị to the south, Khammouane of Laos to the west and the Gulf of Tonkin (South China Sea) to the east.

On June 12, 2025, Quảng Bình was merged into Quảng Trị.
