A megalopolis (/ˌmɛɡəˈlɒpəlɪs/), sometimes called a megapolis; also megaregion, or supercity, is typically defined as a group of two or more roughly adjacent metropolitan areas, which may be somewhat separated or may merge into a continuous urban region. The megalopolis concept became highly influential as it introduced a new, larger scale in thinking about urban patterns and urban growth.
