国际食品法典委员会（英文：Codex Alimentarius Commission，简称CAC，又称Codex），名称源自拉丁文，其中Codex意为“表册、簿籍、案卷、法典等”；Alimentarius意为“卫生者、可供食料者”。

CAC是联合国粮食及农业组织（FAO）和世界卫生组织（WHO）于1963年联合设立的政府间国际组织，专门负责协调政府间的食品标准，创建一套完整的食品国际标准体系。CAC目前有186个成员国，覆盖全球98%的人口。

The Codex Alimentarius (Latin for "Food Code") is a collection of internationally recognized standards, codes of practice, guidelines, and other recommendations relating to foods, food production, and food safety.

Its name is derived from the Codex Alimentarius Austriacus. Its texts are developed and maintained by the Codex Alimentarius Commission, a body that was established in early November 1961 by the Food and Agriculture Organization of the United Nations (FAO), was joined by the World Health Organization (WHO) in June 1962, and held its first session in Rome in October 1963. The Commission's main goals are to protect the health of consumers and ensure fair practices in the international food trade. The Codex Alimentarius is recognized by the World Trade Organization as an international reference point for the resolution of disputes concerning food safety and consumer protection.
