Eastern Hemisphere, part of Earth east of the Atlantic Ocean and west of North and South America. It includes Europe, Asia, Australia, and Africa. Longitudes 20° W and 160° E are often considered its boundaries. Some geographers, however, define the Eastern Hemisphere as being the half of Earth that lies east of the Greenwich meridian (prime meridian, 0° longitude) continuing to the 180th meridian.
