Vinh is the biggest city and economic and cultural center of North-Central Vietnam. Vinh is the capital of Nghệ An Province, and is a key point in the East–West economic corridor linking Myanmar, Thailand, Laos and Vietnam. The city is situated in the Southeast of the province, alongside the Lam River and is located on the main north–south transportation route of Vietnam, easily accessible by highway, railroad, boat and air. The recently expanded Vinh International Airport is served daily by four carriers: Vietnam Airlines, VietJet Air, Bamboo Airways and Jetstar Pacific. On September 5, 2008, it was upgraded from Grade-II city to Grade-I city, the fifth Grade-I city of Vietnam after Haiphong, Đà Nẵng and Huế. Vinh is the most populous city in the North Central Coastal region, with over 490,000 residents. The city is bordered by Nghi Loc district to the north and east, Hung Nguyen district to the west, and Nghi Xuan district in Hà Tĩnh Province to the south. Vinh is about 300 kilometres (190 mi) south of Hanoi and 1,400 kilometres (870 mi) north of Ho Chi Minh City. The total area of Vinh city is 104.97 square kilometres (40.53 sq mi), and includes 16 urban wards and 9 suburban communes.

The North–South railway is the principal railway line serving the country of Vietnam. It is a single-track metre gauge line connecting the capital Hanoi in the north to Ho Chi Minh City in the south, for a total length of 1,726 km (1,072 mi). Trains travelling this line are sometimes referred to as the Reunification Express, although no particular train carries this name officially. The line was established during French colonial rule, and was completed over a period of nearly forty years, from 1899 to 1936. As of 2005, 191 of Vietnam's 278 railway stations were located along the North–South line.
