The term "mainland" typically refers to the principal landmass of a region, often distinguishing it from islands. For example, in the context of the United States, the "mainland" usually refers to the contiguous states, excluding Alaska and Hawaii. In other contexts, such as in reference to China, it refers to the part of the country that is not made up of its islands. Specific names can vary depending on the geographical context in which "mainland" is used.
