Started in October 2002, Chinese Wikipedia had over 270,000 articles as of September 2009 and 400,374 articles as of March 8, 2012. It has 74 administrators, including 21 from mainland China, 15 from Taiwan, and 16 from Hong Kong.

Chinese Wikipedia is the third largest online Chinese encyclopedia after Hudong and Baidu Baike.

Chinese Wikipedia was established along with 12 other Wikipedias in May 2001. At the beginning, however, the Chinese Wikipedia did not support Chinese characters, and had no encyclopedic content.

In October 2002 the first Chinese-language page was written, the Main Page. A software update on October 27, 2002 allowed Chinese language input. The domain was set to be zh.wikipedia.org. On November 17, 2002, Mountain translated the Computer science article into zh:计算机科学, thus creating its first real encyclopedic article.
