The Hemispheres of the Earth in geography and cartography refer to any bipartite division of the globe into a hemisphere (from Ancient Greek ἡμισφαίριον hēmisphairion meaning "half of a sphere").

Division of the Earth by the equator and prime meridian.

The most common such divisions are by latitudinal or longitudinal markers:

The East-West division can also be seen in a cultural sense -- the cultural hemispheres.

However, other schemes have sought to divide the planet in a way that maximizes the preponderance of one geographic feature or another in each division:

  • Land-Water
    • Land hemisphere, the hemisphere on the Earth containing the largest possible area of land
    • Water hemisphere, the hemisphere on the Earth containing the largest area of water
