The China National Highways (CNH/Guodao) (simplified Chinese: 中华人民共和国国道; traditional Chinese: 中華人民共和國國道; pinyin: Zhōnghuá Rénmín Gònghéguó Guódào) is a network of trunk roads across mainland China. Established to facilitate transportation and economic development, the system includes north-south and east-west arterial highways, expressways, and local roads. By 2024, the network encompasses over 1.9 million kilometers of highways, making it one of the most extensive in the world. Key milestones include the completion of major expressways by 2008 and ongoing expansions to enhance connectivity, especially in western and less developed areas.

Apart from the expressways of China that are planned and constructed later, most of the CNH are not controlled-access highways.
