Mainland China, Continental China, the Chinese mainland or simply the mainland, is a geopolitical term that refers to the area under the jurisdiction of the People's Republic of China (PRC) on the Asian mainland. This term excludes the PRC Special Administrative Regions of Hong Kong and Macau.

There are two terms in Chinese for "mainland". Namely, Dalu (simplified Chinese: 大陆; traditional Chinese: 大陸), which means continent, and Neidi (Chinese: 内地), literally inner land. In the PRC, the usage of the two terms are generally interchangeable and there is no prescribed method of reference in any jurisdiction. To emphasize "equal footing" in cross-strait relations, the term is used in official contexts with reference to Taiwan, with the PRC referring to itself as "the mainland side" (as opposed to "the Taiwan side"). But in its relations with Hong Kong and Macau, the PRC government refers to itself as "the Central People's Government".

In Taiwan, the term "mainland China" is often used to refer to the PRC (Hong Kong and Macau excluded), especially by the Kuomintang (KMT, "Chinese Nationalist Party") and its supporters, who share the view that China encompasses both sides of the Taiwan Strait. Since the KMT was the long-time ruling party in Taiwan, the term is in mainstream use in Taiwan and often has no political implications. In contrast, supporters of Taiwan independence will refer to the PRC as "China", intending Taiwan to represent a separate place or political entity and avoid the term mainland China because it implies that Taiwan is part of China.
