Zhongguancun (Chinese: 中关村) is a major technology hub in the Haidian District, Beijing, China.

Zhongguancun occupies a band between the northwestern Third Ring Road and the northwestern Fourth Ring Road in the northwestern part of Beijing. Zhongguancun is sometimes known as China's Silicon Valley. The place is also the center of the Beijing-Tianjin-Shijiazhuang Hi-Tech Industrial Belt.

Chen Chunxian envisioned Zhongguancun, which became a well-known technology hub 30 years later. Chunxian, a member of the Chinese Academy of Sciences (CAS), conceived of a Silicon Valley in China following a government-sponsored trip to Boston and Silicon Valley, United States.

Zhongguancun became known as "Electronics Avenue" (simplified Chinese: 电子一条街; traditional Chinese: 電子一條街; pinyin: Diànzǐ Yītiáojiē) in the early 1980s, due to its information technology markets along a central, crowded street.

Zhongguancun was recognized by the central government of China in 1988, and officially named "Beijing High-Technology Industry Development Experimental Zone". In 1999, Zhongguancun became the "Zhongguancun Science & Technology Zone" with seven parks: Haidian, Fengtai, Changping, Electronics City (in Chaoyang), Yizhuang, Desheng, and Jianxiang. The original Zhongguancun became known as the Haidian Park of the Zhongguancun Zone.

Zhongguancun has an association with China's two most prestigious universities, Peking University and Tsinghua University, along with Beijing Normal University and the Chinese Academy of Sciences, all of which are in close proximity.

Secondary schools in Zhongguancun include the Affiliated High School of Peking University and the High School Affiliated to Renmin University of China.

The Zhongguancun Administrative Committee oversees the city. The State Administration of Foreign Experts Affairs (SAFEA) has its headquarters in Zhongguancun.
