List of geographic interiors

Coastal regions of a territory are often the most densely populated due to their greater economic productivity or colonial history. This leads to a contrast with the interior of the territory, which is (or was) sparsely populated. Examples include:
 * Australian Interior or Interior of Australia, a vast undefined area corresponding very approximately to land that is 200 km to 300 km and more from the coast.
 * British Columbia Interior, commonly called "The Interior", the inland areas of British Columbia, Canada, including but not limited to:
 * The Interior Plateau, official name of the parts of British Columbia between the Coast Mountains and the Columbia Mountains and the Canadian Rockies, and south of the Interior Mountains
 * The Columbia Plateau, Washington, USA, sometimes referred to as the "Interior Plateau"
 * The Alaska Interior, a largely wilderness area, encompassing most of the state
 * Interior Division, an administrative division of Sabah, east Malaysia, on the island of Borneo
 * U.S. Interior Highlands, a mountainous region spanning eastern Oklahoma, western and northern Arkansas, southern Missouri, and the extreme southeast corner of Kansas
 * Interior Plains, a vast physiographic region that spreads across the Laurentian craton of North America
