Đồng Nai is situated in southeastern Vietnam and bordered by: Bình Thuận, Lâm Đồng, Bình Dương and Bình Phước, Bà Rịa–Vũng Tàu, and Ho Chi Minh City (Saigon). Đồng Nai province has an advanced traffic system with many backbone national roads crossing, such as: National route 1A, national route 20, National route 51, North–South railway lines; Located adjacent to the Saigon Port and Tan Son Nhat International Airport, it offers many advantages to economic activities in the area. Its location is very important for the development of the Southern economic main hub and a junction of the South Eastern and Tây Nguyên Highland.

Đồng Nai Province is based essentially on the system of lakes, dams and rivers, of which Trị An Lake with 323 km² and over 60 rivers, rivulets and canals are very favorable for the development of a number of aquatic products: raft bred fish and shrimp. The seasonal tropical forests are protected in Cát Tiên National Park, located on the north of Đồng Nai and the adjacent Vĩnh Cửu Nature Reserve; the former has been recognized internationally as a significant biosphere reserve. From the mountainous area, Đồng Nai River, Vietnam's largest internal waterway, flows southeast through Biên Hòa City, Ho Chi Minh City, and villages along its way. This river plays an important role on supplying fresh water for the whole area.


Đồng Nai lies in the monsoon tropical zone and is affected by the north-east and south-west monsoon. It is also under the influence of Pacific Ocean tropic atmosphere between April and October. Climate is divided in two distinct seasons. The rainy season lasts from March or April to November and the dry season from December to March or April of the following year. Average temperature is between 23.9 and 29.0 °C, much lower than standard level of the tropical regions (26-30 °C). Its annual rainfall is quite high with 1,500 - 2,700 mm.

On average, the weather is sunny for 4.0-9.5 hours a day and does not exceed 11.5 hours per day, even on the hottest and sunniest days. Total rainy days within a year are between 120 and 170 days (standard level of tropical region is 150–160 days) with total rainfall of some 1,500 - 2,750 mm. The average humidity is around 80 - 82% and humidity in the dry season is 10-12%, lower than that of the rainy season; humidity varies considerably between areas.

Đồng Nai Province's weather with regular sunshine, rain, and high humidity, equally found in the localities, facilitates agricultural production and development of industry and cultural and tourism activities.


Đồng Nai is plentiful with forest resources, granite mines, construction stone, clay, kaolin, pozzolan, sand, gravel, etc.


Đồng Nai is one of Vietnam's most populous provinces (ranked fifth) with a population of 2,838,600 in 2014.[1] Its population has been growing rapidly in recent years, mainly driven by migrant workers coming to the province to work in factories. Population growth was 1.95% in 2005, between 2.5% from 2008 to 2010 and 3.5% in 2011. Net migration contributed 2.2% to this figure.[2] Đồng Nai is second only to Bình Dương Province in both population growth and net migration.

The population of Đồng Nai is primarily the dominant Kinh (Viet) ethnicity, although there are residents of the Chinese, Stieng, Mạ, Nùng, Tay, and Cham minorities.


Đồng Nai has made significant progress in upgrading its transport infrastructure, especially roads. National highways in the province have a total length of 244.5 km and have been improved and widened up to level 1 and 2 standards (National Highway No 5 and 6) or up to third grade like National Highway No 20 to Đà Lạt. The total roads system in the province is 3.339 kilometers long, of which almost 700 kilometers are tar roads. All communes and wards are connected to the road network.

Under scheme in the near future, highways to Bà Rịa–Vũng Tàu Province and Ho Chi Minh City, a railway connecting Biên Hòa to Vũng Tàu, upgraded provincial roads No 726 and connecting national highway No 20 and No 1 with national highway No 51 will create a complete system, promoting socioeconomic development in the province and region.

A new airport, Long Thanh International Airport, is planned for construction in Long Thanh district, Đồng Nai, approximately 40 km northeast of Ho Chi Minh City. Upon completion, it will handle international flights in place of Tan Son Nhat International Airport, which will serve domestic flights.

Đồng Nai is one of Vietnam's main manufacturing centers and one of the most developed provinces.


Despite its strong focus on industrial development, Đồng Nai still has a substantial agricultural sector. Agricultural land accounts for 47% of the province's area as of 2011, a total of 277,600ha.[2] This is lower than in other provinces in the Southeast region, except for Ho Chi Minh City. Cereals were grown on 118,600ha in 2011, an area that has been decreasing gradually in recent years, from 139,300ha in 2005.[2] Output of rice has however remained stable and was at 335,200t in 2011. The province also produced 305,300t of maize, making it the largest producer of maize outside the country's mountainous regions and contributing 6.3% to the national maize output.[2] Đồng Nai also produced 619,700t of sugar cane (3.5% of the national output), sweet potatoes and cassava.[2]

Đồng Nai is the largest livestock producer among Vietnam's provinces and plans to further invest in the sector.[3] The government reserved 15,000ha for livestock farming in 2012, mostly for poultry and pigs.[4] In 2011 there were 1.33 million pigs and 10.655 million poultry.[2] Despite not being located along the coast, Đồng Nai produced 41,600t of fishery products in 2011. Over 90% of this was produced in 33,500ha of aquaculture farms.[2] This makes Đồng Nai the largest aquaculture producer outside the Mekong Delta.


Đồng Nai is one of Vietnam's main manufacturing centers. It has attracted 9.1% of FDI into Vietnam by 2011, an accumulated US$18.2 billion, the fourth largest after Ho Chi Minh City, Bà Rịa–Vũng Tàu Province and Hanoi.[2] Industrial gross output in 2011 was VND 314 trillion, 10.6% of the national value.[2] It has received a broad range of FDI projects, including a Bosch auto component plant,[5] a Toshiba motor plant,[6] a PepsiCo beverage factory,[7] a Posco steel plant,[8] and a Nestlé coffee factory.[9]


As defined by a 2008 World Bank survey, the province is one of the five most polluted in Vietnam.[10]
