Changchun is the capital and largest city of Jilin Province in China. Lying in the center of the Songliao Plain, Changchun is administered as a sub-provincial city, comprising 7 districts, 1 county and 3 county-level cities. According to the 2020 census of China, Changchun had a total population of 9,066,906 under its jurisdiction. The city's metro area, comprising 5 districts and 1 development area, had a population of 5,019,477 in 2020, as the Shuangyang and Jiutai districts are not urbanized yet. It is one of the biggest cities in Northeast China, along with Shenyang, Dalian and Harbin.

The name of the city means "long spring" in Chinese. Between 1932 and 1945, Changchun was renamed Xinjing (Chinese: 新京; pinyin: Xīnjīng; lit. 'new capital') or Hsinking by the Kwantung Army as it became the capital of the Imperial Japanese puppet state of Manchukuo, occupying modern Northeast China. After the foundation of the People's Republic of China in 1949, Changchun was established as the provincial capital of Jilin in 1954.

Known locally as China's "City of Automobiles", Changchun is an important industrial base with a particular focus on the automotive sector. Because of its key role in the domestic automobile industry, Changchun was sometimes referred to as the "Detroit of China." Apart from this industrial aspect, Changchun is also one of four "National Garden Cities" awarded by the Ministry of Construction of P.R. China in 2001 due to its high urban greening rate.

Changchun is also one of the top 40 cities in the world by scientific research as tracked by the Nature Index according to the Nature Index 2020 Science Cities. The city is home to several major universities, notably Jilin University and Northeast Normal University, members of China's prestigious universities in the Double First-Class Construction.

Changchun was initially established on imperial decree as a small trading post and frontier village during the reign of the Jiaqing Emperor in the Qing dynasty. Trading activities mainly involved furs and other natural products during this period. In 1800, the Jiaqing Emperor selected a small village on the east bank of the Yitong River and named it "Changchun Ting".

At the end of the 18th century peasants from overpopulated provinces such as Shandong and Hebei began to settle in the region. In 1889, the village was promoted into a city known as "Changchun Fu".

In May 1898, Changchun got its first railway station, located in Kuancheng, part of the railway from Harbin to Lüshun (the southern branch of the Chinese Eastern Railway), constructed by the Russian Empire.

After Russia's loss of the southernmost section of this branch as a result of the Russo-Japanese War of 1904–1905, the Kuancheng station (Kuanchengtze, in contemporary spelling) became the last Russian station on this branch. The next station just a short distance to the south—the new "Japanese" Changchun station—became the first station of the South Manchuria Railway, which now owned all the tracks running farther south, to Lüshun, which they re-gauged to the standard gauge (after a short period of using the narrow Japanese 3 ft 6 in (1,067 mm) gauge during the war).

A special Russo-Japanese agreement of 1907 provided that Russian gauge tracks would continue from the "Russian" Kuancheng Station to the "Japanese" Changchun Station, and vice versa, tracks on the "gauge adapted by the South Manchuria Railway" (i.e. the standard gauge) would continue from Changchun Station to Kuancheng Station.

An epidemic of pneumonic plague occurred in surrounding Manchuria from 1910 to 1911, known as the Manchurian plague. It was the worst-ever recorded outbreak of pneumonic plague which was spread through the Trans-Manchurian railway from the border trade port of Manzhouli. This turned out to be the beginning of the large pneumonic plague pandemic of Manchuria and Mongolia which ultimately claimed 60,000 victims.

The Treaty of Portsmouth formally ended the Russo-Japanese War of 1904–05 and saw the transfer and assignment to the Empire of Japan in 1906 the railway between Changchun and Port Arthur, and all its branches.

Having realized the strategic importance of Changchun's location with respect to Japan, China and Russia, the Japanese Government sent a group of planners and engineers to Changchun to determine the best site for a new railway station.

Without the consent of the Chinese Government, Japan purchased or seized from local farmers the land on which the Changchun Railway Station was to be constructed as the centre of the South Manchuria Railway Affiliated Areas (SMRAA). In order to turn Changchun into the centre for extracting the agricultural and mineral resources of Manchuria, Japan developed a blueprint for Changchun and invested heavily in the construction of the city.

At the beginning of 1907, as the prelude to, and preparation for, the invasion and occupation of China, Japan initiated the planning programme of the SMRAA, which embodied distinctive colonial characteristics. The guiding ideology of the overall design was to build a high standard colonial city with sophisticated facilities, multiple functions and a large scale.

Accordingly, nearly ¥7 million on average was allocated on a year-by-year basis for urban planning and construction during the period 1907 to 1931.

The comprehensive plan was to ensure the comfort required by Japanese employees on Manchurian Railways, build up Changchun into a base for Japanese control of the whole Manchuria in order to provide an effective counterweight to Russia in this area of China.

The city's role as a rail hub was underlined in its planning and construction, the main design concepts of which read as follows: under conventional grid pattern terms, two geoplagiotropic boulevards were newly carved eastward and westward from the grand square of the new railway station. The two helped form two intersections with the gridded prototypes, which led to two circles of South and West. The two sub-civic centres served as axes on which eight radial roads were blazed that took the shape of a sectoral structure.

At that time, the radial circles and the design concept of urban roads were quite advanced and scientific. It activated to great extent the serious urban landscapes as well as clearly identifying the traditional gridded pattern.

With the new Changchun railway station as its centre, the urban plan divided the SMRAA into various specified areas: residential quarters 15%, commerce 33%, grain depot 19%, factories 12%, public entertainment 9%, and administrative organs (including a Japanese garrison) 12%. Each block provided the railway station with supporting and systematic services dependent on its own functions.

In the meantime, a comprehensive system of judiciary and military police was established which was totally independent of China. That accounted for the widespread nature of military facilities within the urban construction area of 3.967 km (1.532 sq mi), such as the railway garrison, the gendarmerie and the police department, with its 18 local police stations.

Perceiving Changchun as a tabula rasa upon which to construct new and sweeping conceptions of the built environment, the Japanese used the city as a practical laboratory to create two distinct and idealized urban milieus, each appropriate to a particular era. From 1906 to 1931, Changchun served as a key railway town through which the Japanese orchestrated an informal empire. Between 1932 and 1945, the city became home to a grandiose new Asian capital. Yet, while the façades in the city and later the capital contrasted markedly, along with the attitudes of the state they upheld, the shifting styles of planning and architecture consistently attempted to represent Japanese rule as progressive, beneficent, and modern.

The development of Changchun, in addition to being driven by the railway system, suggested an important period of the Northeast modern architectural culture, reflecting Japanese urban design endeavours and revealing that county's ambition to invade and occupy China. Japanese architecture and culture had been widely applied to Manchukuo to highlight the special status of the Japanese puppet. Urban planning clearly stems from a culture, be it aggressive or creative. Changchun's planning and construction process serves as a good example.

Changchun expanded rapidly as the junction between of the Japanese-owned South Manchurian Railway and the Russian-owned Chinese Eastern Railway, remaining the break of gauge point between the Russian and standard gauges into the 1930s,

On 10 March 1932 the capital of Manchukuo, a Japan-controlled puppet state in Manchuria, was established in Changchun. The city was then renamed Hsinking (Chinese: 新京; pinyin: Xīnjīng; Wade–Giles: Hsin-ching; Japanese:Shinkyō; literally "New Capital") on 13 March. The Emperor Puyi resided in the Imperial Palace (Chinese: 帝宮; pinyin: Dì gōng) which is now the Museum of the Manchu State Imperial Palace. During the Manchukuo period, the region experienced harsh suppression, brutal warfare on the civilian population, forced conscription and labor and other Japanese sponsored government brutalities; at the same time a rapid industrialisation and militarisation took place. Hsinking was a well-planned city with broad avenues and modern public works. The city underwent rapid expansion in both its economy and infrastructure. Many of buildings built during the Japanese colonial era still stand today, including those of the Eight Major Bureaus of Manchukuo (Chinese: 八大部; pinyin: Bādà bù) as well as the Headquarters of the Japanese Kwantung Army.

Hsinking was the only Direct-controlled municipality (特别市) in Manchukuo after Harbin was incorporated into the jurisdiction of Binjiang Province. In March 1932, the Inspection Division of South Manchuria Railway started to draw up the Metropolitan Plan of Great Hsinking (simplified Chinese: 大新京都市计画; traditional Chinese: 大新京都市計畫; pinyin: Dà xīn jīngdū shì jìhuà). The Bureau of capital construction (国都建设局; 國都建設局; Guódū jiànshè jú) which was directly under the control of State Council of Manchukuo was established to take complete responsibility of the formulation and the implementation of the plan. Kuniaki Koiso, the Chief of Staff of the Kwantung Army, and Yasuji Okamura, the Vice Chief-of-Staff, finalized the plan of a 200 km (77 sq mi) construction area. The Metropolitan Plan of Great Hsinking was influenced by the renovation plan of Paris in the 19th century, the garden city movement, and theories of American cities' planning and design in the 1920s. The city development plan included extensive tree planting. By 1934 Hsinking was known as the Forest Capital with Jingyuetan Park built, which is now China's largest Plantation and a AAAA-rated recreational area.

In accordance with the Metropolitan Plan of Great Hsinking, the area of publicly shared land (including the Imperial Palace, government offices, roads, parks and athletic grounds) in Hsinking was 47 km (18 sq mi), whilst the area of residential, commercial and industrial developments was planned to be 53 km (20 sq mi). However, Hsinking's population exceeded the prediction of 500,000 by 1940. In 1941, the Capital Construction Bureau modified the original plan, which expanded the urban area to 160 km (62 sq mi). The new plan also focused on the construction of satellite towns around the city with a planning of 200 m (2,200 sq ft) land per capita. Because the effects of war, the Metropolitan Plan of Great Hsinking remained unfinished. By 1944, the built up urban area of Hsinking reached 80 km (31 sq mi), while the area used for greening reached 70.7 km (27.3 sq mi). As Hsinking's city orientation was the administrative center and military commanding center, land for military use exceeded the originally planned figure of 9 percent, while only light manufacturing including packing industry, cigarette industry and paper-making had been developed during this period. Japanese force also controlled Hsinking's police system, instead of Manchukuo government. Major officers of Hsinking police were all ethnic Japanese.

The population of Hsinking also experienced rapid growth after being established as the capital of Manchukuo. According to the census in 1934 taken by the police agency, the city's municipal area had 141,712 inhabitants. By 1944 the city's population had risen to 863,607, with 153,614 Japanese settlers. This population made Hsinking the third largest metropolitan city in Manchukuo after Mukden and Harbin, as the metropolitan mainly focused on military and political function.

In 1936, the Imperial Japanese Army established Unit 100 to develop plague biological weapons, although the declared purpose of Unit 100 was to conduct research about diseases originating from animals. During the Second Sino-Japanese War (1937–1945) and World War II the headquarters of Unit 100 ("Wakamatsu Unit") was located in downtown Hsinking, under command of veterinarian Yujiro Wakamatsu. This facility was involved in research of animal vaccines to protect Japanese resources, and, especially, biological-warfare. Diseases were tested for use against Soviet and Chinese horses and other livestock. In addition to these tests, Unit 100 ran a bacteria factory to produce the pathogens needed by other units. Biological sabotage testing was also handled at this facility: everything from poisons to chemical crop destruction.

On 20 August 1945 the city was captured by the Soviet Red Army and renamed Changchun. The Russians maintained a presence in the city during the Soviet occupation of Manchuria until 1946.

National Revolutionary Army forces under Zheng Dongguo occupied the city in 1946, but were unable to hold the countryside against Lin Biao's People's Liberation Army forces during the Chinese Civil War. The city fell to the Chinese Communist Party in 1948 after the five-month Siege of Changchun, and the communist victory was a turning point which allowed an offensive to capture the remainder of Mainland China. Between 10 and 30 percent of the civilian population starved to death under the siege; estimates range from 150,000 to 330,000. As of 2015 the PRC government avoids all mention of the siege.

Renamed Changchun by the People's Republic of China government, it became the capital of Jilin in 1954. The Changchun Film Studio is also one of the remaining film studios of the era. Changchun Film Festival has become a unique gala for film industries since 1992.

From the 1950s, Changchun was designated to become a center for China's automotive industry. Construction of the First Automobile Works (FAW) began in 1953 and production of the Jiefang CA-10 truck, based on the Soviet ZIS-150 started in 1956. Soviet Union lent assistance during these early years, providing technical support, tooling, and production machinery. In 1958, FAW introduced the famous Hongqi (Red Flag) limousines This series of cars are billed as "the official car for minister-level officials".

In 2002, the local television broadcast was hijacked by a small group of Falun Gong practitioners. These events were depicted in the documentary Eternal Spring.

Changchun hosted the 2007 Winter Asian Games.

The most commonly spoken dialect in Changchun is the Northeastern Mandarin, which is originated from the mix of several languages spoken by immigrants from Hebei and Shandong. Then, after the PRC was established, the rapid economic growth in Changchun attracted a huge number of immigrants from various places, so the northeastern dialect spoken in urban areas of Changchun is closer to the Mandarin Chinese than the in rural areas because the immigrants had a great impact on the northeastern dialect spoken in urban areas.

Changchun has four major religions: Buddhism, Taoism, Christianity, and Islam. There are 396 government-approved places for religious activities and worship services.

The temples in Changchun include Changchun Wanshou Temple, Baoguo Prajna Temple, Baiguo Xinglong Temple, Pumen Temple, Big Buddha Temple, Changchun Temple, Changchun Catholic Church, Changchun West Wuma Road Christian Church, and Changchun City Mosque.

Shamanism had been circulated in Northeast China during ancient times and was believed by many Manchus. Now the shamanism and the study of it have become an important cultural heritage of the region.

Jilin Provincial Museum, a national first-grade museum, is located in Changchun. The museum was moved to Changchun from Jilin City after the transfer of the provincial government seat.

Changchun is a very compact city, planned by the Japanese with a layout of open avenues and public squares. The city is developing its layout in a long-term bid to alleviate pressure on limited land, aid economic development, and absorb a rising population. According to a draft plan up until 2020, the downtown area will expand southwards to form a new city center around Changchun World Sculpture Park, Weixing Square and their outskirts, and the new development zone. For the north of the city, there is a new development zone called "Changchun New Area", locate near the North Lake Park.

Changchun has two passenger rail stations, all conventional trains and some high-speed trains stop at the central Changchun railway station (simplified Chinese: 长春站; traditional Chinese: 長春站), which is connected by Beijing-Harbin Railway, Changchun-Hunchun intercity railway and several railway lines. The station has multiple daily departures to other cities in the province and northeast area, such as Jilin City, Yanji, Harbin, Shenyang, and Dalian, as well as other major cities throughout the country such as Beijing, Shanghai and Guangzhou. The new Changchun West railway station, situated in the western end of urbanized area, is the station mainly for the high-speed trains of the Harbin–Dalian high-speed railway.

Changchun is served by a comprehensive bus system, which having more than 250 bus route, most buses charge 1-2 yuan per ride.

Changchun is one of the few cities preserving the historic tram system in China. The tram system first opened in 1941, having 6 lines covering almost 53 km at its peak. But after several route adjustments, there is only one line left since the 2000s. A new branch line is opened in 2014, which links the new Changchun West Railway Station. The whole system is now operated under the bus system of Changchun.

Changchun Rail Transit is a rapid transit system of Changchun, combining light rail lines and metro lines. Its first line was opened on 30 October 2002, making Changchun the fifth metropolitan city in China to open rail transit.

Till November 2018, there are 5 lines in Changchun, including Line 1, Line 2, Line 3, Line 4, and Line 8. Changchun railway covers about 100.17 kilometers.
