The China Association for Science and Technology (CAST; Chinese: 中国科学技术协会; pinyin: Zhōngguó Kēxué Jìshù Xiéhuì) is a people's organization of Chinese scientists and engineers, which is composed of multiple national professional societies and hundreds of branches at various local and international levels.

[2] Its stated goal is to act as a link between the science and technology community and the Chinese Communist Party (CCP) and government.

[2] CAST is a constituent member of the Chinese People's Political Consultative Conference (CPPCC).

[9][10] Since 2014, CAST has established a series of "offshore entrepreneurial bases" in multiple countries that have been described as a "hub-and-spoke model where a base in China incubates and commercializes innovative ideas sourced from a network of offshore innovation centers in foreign countries.

"[13] Science & Technology Review was begun in 1980 in the United States and is the official journal of CAST.
