Fujian (help·info) (Chinese: 福建), formerly romanised as Fukien or Foukien, is a province on the southeast coast of mainland China. Fujian is bordered by Zhejiang to the north, Jiangxi to the west, and Guangdong to the south. Taiwan lies to the east, across the Taiwan Strait. The name Fujian came from the combination of Fuzhou and Jianzhou (a former name for Jian'ou) two cities in Fujian, during the Tang Dynasty. With a Han majority, it is one of the most culturally and linguistically diverse provinces in China.

Most of Fujian is administered by the People's Republic of China. However, the archipelagos of Kinmen and Matsu are under the control of the Republic of China (Taiwan). Thus, there are two provinces (in the sense of government organizations; People's Republic of China administrated Fujian Province and Fujian Province of Republic of China.

Recent archaeological discoveries demonstrate that Fujian had entered the Neolithic Age by the middle of the 6th millennium BC. From the Keqiutou site (7450–5590 BP), an early Neolithic site in Pingtan Island located about 70 km southeast of Fuzhou, numerous tools made of stones, shells, bones, jades, and ceramics (including wheel-made-ceramics) have been unearthed, together with spinning wheels, a definitive evidence of weaving.

The Tanshishan (昙石山) site (5500–4000 BP) in suburban Fuzhou spans the Neolithic and Chalcolithic Age where semi-underground circular buildings were found in the lower level. The Huangtulun (黄土崙) site (ca.1325 BC), also in suburban Fuzhou, was of the Bronze Age in character.

This area was also the place for the kingdom of Minyue. The word "Mǐnyuè" was derived by combining "Mǐn" (閩/闽; Pe̍h-ōe-jī: bân), perhaps an ethnic name and associated with the Chinese word for barbarians (蠻/蛮; pinyin: mán; POJ: bân), and "Yuè", after the State of Yue, a Spring and Autumn Period kingdom in Zhejiang Province to the north. This is because the royal family of Yuè fled to Fujian after their kingdom was annexed by the State of Chu in 306 BC. Mǐn is also the name of the main river in this area, but the ethnonym is probably earlier.

Minyue was a de facto kingdom until the emperor of Qin Dynasty, the first unified imperial Chinese state, abolished the status. In the aftermath of the fall of the Qin Dynasty, however, civil war broke out between two warlords, Xiang Yu and Liu Bang; the Minyue king Wuzhu sent his troops to fight side-by-side with Liu Bang, and his gamble paid off. Liu Bang was victorious, and founded the Han Dynasty; in 202 BC he restored Minyue's status as a tributary independent kingdom. Thus Wuzhu was allowed to construct his fortified city in Fuzhou as well as a few locations in the Wuyi Mountains, which have been excavated in recent years. His kingdom extended beyond the borders of contemporary Fujian into eastern Guangdong, eastern Jiangxi, and southern Zhejiang.

After the death of Wuzhu, Minyue maintained its militant tradition and launched several expeditions against their neighboring kingdoms in Guangdong, Jiangxi, and Zhejiang, mostly in the 2nd century BC, only to be stopped by the Han Dynasty. The Han emperor eventually decided to get rid of the potential threat by sending in large forces simultaneously from four directions via land and sea in 111 BC. The rulers in Fuzhou surrendered to avoid a futile fight and destruction; thus the first kingdom in Fujian history came to an abrupt end.

The Han Dynasty collapsed at the end of the 2nd century AD, paving the way for the Three Kingdoms era. Sun Quan, the founder of the Kingdom of Wu, spent nearly twenty years subduing the Shan Yue people, the branch of the Yue living in mountains.

The first wave of immigration of the noble class arrived in the province in the early 4th century AD when the Western Jin Dynasty collapsed and the north was torn apart by invasions by nomadic peoples from the north, as well as civil war. These immigrants were primarily from eight families in central China: Lin (林), Huang (黄), Chen (陈), Zheng (郑), Zhan (詹), Qiu (邱), He (何), and Hu (胡). The first four remain as the major surnames of modern Fujian.

Nevertheless, isolation from nearby areas owing to rugged terrain contributed to Fujian's relatively backward economy and level of development, despite major population boost from northern China during the "barbarian" invasions. Population density in Fujian remained low compared to the rest of China. Only two commanderies and sixteen counties were established by the Western Jin Dynasty. Like other southern provinces such as Guangdong, Guangxi, Guizhou, and Yunnan, Fujian often served as a destination for exiled prisoners and dissidents at that time.

During the Southern and Northern Dynasties era, the Southern Dynasties reigned south of the Yangtze River, including Fujian.

The Tang Dynasty (618–907) oversaw the next golden age of China. As the Tang Dynasty ended, China was torn apart in the period of the Five Dynasties and Ten Kingdoms. During this time, a second major wave of immigration arrived in the safe haven of Fujian, led by general Wang, who set up an independent Kingdom of Min with its capital in Fuzhou. After the death of the founding king, however, the kingdom suffered from internal strife, and was soon swallowed up by Southern Tang, another southern kingdom.

Quanzhou was blooming into a seaport under the reign of the Min Kingdom, and may have been the largest seaport in the Eastern hemisphere. In the early Ming Dynasty, Quanzhou was the staging area and supply depot of Zheng He's naval expeditions. Further development was severely hampered by the sea trade ban of the Ming Dynasty, and the area was superseded by nearby ports of Guangzhou, Hangzhou, Ningbo and Shanghai despite the lifting of the ban in 1550. Large scale piracy by Wokou (Japanese pirates) was eventually wiped out by Chinese military and Japanese authority of Toyotomi Hideyoshi.

Late Ming and early Qing Dynasty symbolized an era of large influx of refugees and another 20 years of sea trade ban under the Kangxi Emperor, a measure intended to counter the refuge Ming government of Koxinga in Taiwan. Incoming refugees, however, did not translate into a major labor force owing to their re-migration into prosperous regions of Guangdong province. In 1689, the Qing dynasty officially incorporated Taiwan into Fujian province. Settlement of Taiwan by Han Chinese followed, and the majority of people in Taiwan are descendants of emigrants from Southern Fujian. After Taiwan was separated into its own province in 1885 and ceded to Japan in 1895, Fujian arrived at its present extent. It was substantially influenced by the Japanese after the Treaty of Shimonoseki of 1895 until the Sino-Japanese War (1937-1945) of WWII.

Owing to the mountainous landscape, Fujian was the most secluded province of the PRC in eastern China due to the lack of rail and underdeveloped networks of paved roads before the 1950s. The first railway to the province, the Yingtan-Xiamen Railway, was completed in 1957. Despite its secluded location, Fujian has had a strong academic tradition since the Southern Song Dynasty. At the time, north China was occupied by the Jurchen Jin Dynasty, which caused a shift of the cultural center of China to the south, benefiting Fuzhou and other southern cities. In the Chinese Academy of Science and Chinese Academy of Engineering, there are more members from Fuzhou than from any other city. In addition, it should also be pointed out that the slow development of Fujian in its early days has proven a blessing for the province's ecology; today, the province has the highest forest coverage rate and the most diverse biosphere in China whereas central China suffers from severe overpopulation and displays severe signs of soil erosion accompanied by frequent droughts and floods due to lack of forest coverage.

Since the late 1970s, the economy of Fujian along the coast has greatly benefited from its geographic and cultural proximity to Taiwan. In 2003, Xiamen ranked number eight GDP per capita among 659 Chinese cities, ahead of Shanghai and Beijing, while Fuzhou ranked no. 21 (number 4 among 30 provincial capitals). The development has been accompanied by a large influx of population from the over-populated areas in the north and west, and much of the farmland and forest as well as cultural heritage sites such as the temples of king Wuzhu have given way to ubiquitous high-rise buildings, and the government faces a challenge at all levels to sustain development while, at the same time, preserving the unique and vital natural and cultural heritage of Fujian.

Because of its mountainous nature and the numerous waves of migration from central China in the course of history, Fujian is one of the most linguistically diverse places in all Han Chinese areas of China. Local dialects can become unintelligible within 10 km. This is reflected in the expression that "if you drive five miles in Fujian the culture changes, and if you drive ten miles, the language does". Classification of these various dialects has confounded linguists. In general, most dialects of Fujian are put into a broad Min category, then subdivided into Min Bei, Min Dong, Min Zhong, Min Nan, Pu Xian, and Shao Jiang. (The seventh subdivision of Min, Qiong Wen, is not spoken in Fujian.) The Fuzhou dialect is part of Min Dong, but some linguists classify it as Min Bei; the Amoy language is part of Min Nan. Hakka, another subdivision of spoken Chinese, is spoken around Longyan by the Hakka people who live there.

As is true of other provinces, the official language in Fujian is Mandarin, which is used for communication between people of different localities.

Several regions of Fujian have their own form of Chinese opera. Minju (Fujian Opera) is popular around Fuzhou; Gaojiaxi around Jinjiang and Quanzhou; Xiangju around Zhangzhou; Fujian Nanqu throughout the south, and Puxianxi around Putian and Xianyou County.

Fujian cuisine, with an emphasis on seafood, is one of the eight great traditions of Chinese cuisine. It is composed of traditions from various regions, including Fuzhou cuisine and Min Nan cuisine. The most prestigious dish is Fotiaoqiang (literally "Buddha jumps over the wall"), a complex dish making use of many ingredients, including shark fin, sea cucumber, abalone, and Shaoxing wine (a form of "Chinese alcoholic beverage").

Many famous teas originate from Fujian, including oolong, Wuyi Yancha, and Fuzhou jasmine tea. Fujian tea ceremony is an elaborate way of preparing and serving tea. In fact, the English word "tea" is borrowed from Min nan language. (Mandarin and Cantonese pronounce the word chá.)

Fuzhou bodiless lacquer ware, a famous type of lacquer ware, is noted for using a body of clay and/or plaster to form its shape; the body later removed. Fuzhou is also famous for Shoushan stone carvings.

The province is mostly mountainous, and is traditionally described to be "Eight parts mountain, one part water, and one part farmland" (八山一水一分田). The northwest is higher in altitude, with the Wuyi Mountains forming the border between Fujian and Jiangxi. It is the most forested provincial level administrative region in China, with a 62.96% forest coverage rate in 2009. The highest point of Fujian is Huanggang Peak in the Wuyi Mountains, with an altitude of 2157 m.

Fujian province faces East China Sea to the east, South China Sea to the south, and the Taiwan Strait to the southeast. The coastline is rugged and has many bays and islands. Major islands include Quemoy (controlled by the Republic of China), Haitan Island, and Nanri Island.

The Min River (闽江) and its tributaries cut through much of northern and central Fujian. Other rivers include the Jinjiang River and the Jiulong River. Due to its uneven topography, Fujian has many cliffs and rapids.

Fujian is separated from Taiwan by the 180 kilometres (110 mi)-wide Taiwan Strait. Some of the small islands in the Taiwan Strait are also part of the province. Small parts of the province, namely the islands of Quemoy and Matsu, are under the administration of the Republic of China.

Fujian has a subtropical climate, with warm winters. In January the coastal regions average around 7–10 °C (45–50 °F) while the hills average 6–8 °C (43–46 °F). In the summer, temperatures are high, and the province is threatened by typhoons coming in from the Pacific. Average annual precipitation is 1,400–2,000 millimetres (55–79 in).
