Langfang (Chinese: 廊坊; pinyin: Lángfáng), is a prefecture-level city of Hebei Province, which was known as Tianjin Prefecture until 1973. Hebei province was renamed Langfang Prefecture after Tianjin became a municipality and finally upgraded into a prefecture-level city in 1988. Langfang is located approximately midway between Beijing and Tianjin. At the 2010 census, the population of Langfang was 4,358,839, of whom 868,066 lived in the built-up (or metro) area made of Guangyang and Anci districts; its total area is around 6,417.28 km2 (2,477.73 sq mi). Langfang borders Baoding to the southwest, Cangzhou to the south (both prefecture-level cities of Hebei), Beijing to the north and Tianjin to the east. Sanhe City and Dachang Hui County are now conurbated with Beijing, so that they form part of the same built-up area. Langfang is the smallest prefecture-level city of Hebei Province by land area.
Langfang consists of 2 county-level districts, 2 county-level cities, 5 counties, 1 autonomous county, and one economic development district (开发区).

Considering Langfang's position between these two prominent cities, Langfang is a relatively green city. Every 300 to 500 m (980 to 1,640 ft) along the city's major streets are parks where local people stroll and take exercise. Langfang's five-kilometer long pedestrian street is now the longest in China. On the other hand, air pollution is a severe problem and in 2013 it was ranked among the 10 worst cities in China for air pollution, along with 6 other cities in Hebei including Xingtai, Shijiazhuang, Baoding, Handan, Hengshui and Tangshan, are among China's 10 most polluted cities.
The Sanhe exclave, separated from the rest of the province, is a part of Langfang City. The exclave comprises Sanhe City, Xianghe County, and Dachang Hui Autonomous County and is located between the municipalities of Beijing and Tianjin.
On June 26, 1900, during the Boxer Movement, belligerent European forces heading towards Beijing were stopped by Boxers at the Battle of Langfang, and were defeated and forced to turn back to Tianjin. The Chinese forces were victorious.
It was the site of another battle during the Second Sino-Japanese War.
Langfang's economy emphasizes computers and technology and manufacturing. To that effect Langfang is home to an export processing zone, an area for factories, and the Oriental University City (东方大学城), a 4-billion yuan investment that began construction in 1999, where some 30 universities enroll about 50,000 students.
There are two national oil and gas companies based in Langfang. The China Petroleum Pipeline Bureau, the primary builder of pipelines in China, and the ENN Group, a natural gas company, are both based in the city.Langfang Export Processing Zone
The Langfang Export Processing Zone (Langfang EPZ) was established by the State Council in 2005. It has a planned area of 0.5 km2 and commenced operation in October 2008. It is the only state-level development zone in Langfang. Langfang EPZ is located in the Langfang Economic and Technical Development Zone (Langfang ETDZ), which is a province-level development zone. It is 38 km (24 mi) from Beijing's third ring-road, and 50 km (31 mi) from down-town Tianjin. It is 60 km (37 mi) from Beijing Capital International Airport, and 70 km (43 mi) from Tianjin Binhai International Airport, airports which are China's first and twelfth largest airports in terms of cargo transport, respectively. The nation's fourth largest seaport, Tianjin Port, is 105 km (65 mi) from Langfang EPZ.
Langfang does not have its own port or airport, but is well connected. It is only a one-hour drive from Beijing Capital International Airport and the Tianjin New Port. Langfang Railway Station is situated on the Beijing–Harbin Railway.
