The Guozijian (simplified Chinese: 国子监; traditional Chinese: 國子監; pinyin: guózǐjiàn; Wade–Giles: kuo2-tzu3-chien4; literally: "School for the Sons of the State"), sometimes translated as the National School, National Academy, Imperial Academy, Imperial University, Imperial College, Imperial Central School, etc., was the national central institution of higher learning in Chinese dynasties after the Sui. It was the highest institution of learning in China's traditional educational system, with the function of administration of education. In Vietnam, the Imperial Academy (Vietnamese: Quốc Tử Giám) existed after the Lý dynasty. Several notable chairmans of Guozijian in Vietnam were Chu Văn An, Nguyễn Phi Khanh, Vũ Miên, and Trương Công Giai.
Formerly it was called the Taixue, while Taixue for Gongsheng (tribute students) from the populace was still part of Guozijian, along with Guozixue for noble students. The central schools of taixue were established as far back as 3 CE, when a standard nationwide school system was established and funded during the reign of Emperor Ping of Han. Since Sui dynasty it was called Guozijian (Kuotzuchien). In 1905, Guozijian was finally shut down. 
Guozijian were located in the national capital of each dynasty, such as Chang'an, Luoyang and Kaifeng. In early years of Ming, Guozijian was in Nanjing, and then there were two capitals, thus there were two Guozijian, one in Nanjing and one in Beijing. In Qing, Guozijian was in Beijing.
The Guozijian in Beiijng, located at the Guozijian Street in the Dongcheng District, was the imperial college during the Yuan, Ming and Qing dynasties, most of the current buildings of were built during the Ming Dynasty, and it's the last Guozijian in China and is an important national cultural asset.

- During the 1898 reform of the Qing Dynasty, the education and administration of education functions of Guozijian was mainly replaced by the Imperial Capital University (also translated as Imperial University of Peking), later known as Peking University. So some claim Peking University to be the successor of the Guozijian. National Central University (Nanking University) takes Nanking Kuotzuchien in Ming (later Nanking Academy in Qing) as its predecessor.
