Đồng Hới is the capital city of Quảng Bình Province in the north central coast of Vietnam. The city's area is Population as per the 2019 census was 133,672. It borders Quảng Ninh District on the west and south, the South China Sea on the east, Bố Trạch District on the north. It is the closest city to Phong Nha Kẻ Bàng National Park, UNESCO's World Natural Heritage Site, 50 km north.

Archaeological excavation in this area proved that humans lived in what is now Quảng Bình province in the Stone Age. Many artifacts, such as ceramic vases, stone tools, and china, have been unearthed in Quảng Bình. In 1926, French archaeologist Madeleine Colani discovered and excavated many artifacts in caves and grottoes in west mountainous areas of Quảng Bình. She concluded that the Hòa Bình culture existed in this region. Through C14 testing, the artifacts dated back to 10,509 (plus or minus 950) years ago. From Quy Đạt township (Tuyên Hóa District) to south west about 150 m, the Hum grotto contains many stone tools and animal stones from an ancient human community. Inside Khai grotto near the Quy Đạt township, similar artifacts were found, including ceramics from Đông Sơn culture. Additionally, artifacts of the Stone Age were unearthed in grottoes in the Quảng Bình region. Owners of these artifacts lived in the caves and grottoes and hunted for their food. During the time of the Trịnh–Nguyễn War (1558–1775), Vietnam was divided into two countries: Dang Trong (South) and Dang Ngoai (North) with the Gianh River as frontier line. Đồng Hới was an important fortress of the southern Nguyễn lords. The Đồng Hới Wall (Vietnamese: Thành Đồng Hới) was considered the barrier that protected the Nguyễn lords from the attack by the northern Trịnh family. During the First Indochina War (between the French and the Viet Minh in the 1950s), the Đồng Hới airbase was used by the French to attack the Viet Minh in north central Vietnam and the Laotian Pathet Lao army in central and southern Laos. During the Vietnam War, Đồng Hới was heavily devastated by bombardments from United States B 52 bombers due to its location near the 17th parallel and the DMZ between North Vietnam and South Vietnam. On February 11, 1965, bombing destroyed much of the city. The Tam Tòa Church, a Catholic cathedral, was severely damaged. Today the bell tower remains near the town center as a monument. On 19 April 1972, during a major North Vietnam offensive, a task force of four US ships were sailing off the coast of Vietnam — Oklahoma City, Sterett, Lloyd Thomas and Higbee. They were attacked by three North Vietnamese MiG aircraft in the Battle of Đồng Hới. In an attempt to surprise the task force, the MiGs came in low, described as "getting their feet wet." Despite the official stories, they did not surprise the task force, which had spotted them long before engagement range and were ready to shoot. Two ships, Oklahoma City and Sterett, had anti aircraft missiles, while Higbee and Lloyd Thomas were armed with dual purpose guns. All ships were at battle stations. This city is the narrowest land of Vietnam (around 40 km from the east to the west). After the fall of Saigon on 30 April 1975, Quảng Bình province was merged into Bình Trị Thiên province (Bình Trị Thiên is the abbreviation of Quảng Bình, Quảng Trị, and Thừa Thiên provinces). In 1990, Bình Trị Thiên was once again separated into three provinces as it had been before. Đồng Hới then became the capital of Quảng Bình province.
