20th meridian east

The meridian 20° east of Greenwich is a line of longitude that extends from the North Pole across the Arctic Ocean, Europe, Africa, the Atlantic and Indian oceans, the Southern Ocean, and Antarctica to the South Pole.

The 20th meridian east forms a great circle with the 160th meridian west.

Part of Namibia's borders with Botswana and South Africa are defined by the meridian. The boundary between the Atlantic Ocean and the Indian Ocean is defined by the meridian. The meridian defines the eastern limit of the New Swabia area in Queen Maud Land, Antarctica.
