Hanoi, the capital city of Vietnam, is situated in the northern part of the country, specifically in the northwestern region of the Red River Delta — one of Vietnam’s most fertile and historically significant areas. From a geographical perspective, Hanoi lies between 20°34’ and 21°18’ north latitude and 105°17’ to 106°02’ east longitude, placing it at a strategic crossroads between mountainous regions in the north and the coastal lowlands of northern Vietnam.
The location of Hanoi Vietnam gives it exceptional importance in terms of transportation, economics, politics, and national defense. The city is bordered by multiple provinces that strengthen its role as a regional hub. To the north, Hanoi borders Thai Nguyen and Vinh Phuc (now administratively part of Phu Tho). To the south, it connects with Ha Nam (now Ninh Binh) and Hoa Binh, while Bac Giang, Bac Ninh, and Hung Yen lie to the east. To the west, Hanoi borders Hoa Binh and Phu Tho, creating strong interprovincial links in all directions.
Covering a total area of approximately 3,358.6 square kilometers, the capital of Vietnam accounts for nearly 1% of the country’s total land area. Its location along the Red River has historically supported agriculture, trade, and settlement for over a thousand years. Today, this advantageous geographic position allows Hanoi to serve as a vital connector between northern provinces, major economic zones, and international transport corridors linking Vietnam with China and Southeast Asia.
