The supercontinent of Africa-Eurasia (or Afro-Eurasia) is the world's largest land mass and contains around 85% of the human population, which is subdivided into Africa and Eurasia by drawing a line somewhere near the Suez Canal. Historians may subdivide it into Eurasia-North Africa and Sub-Saharan Africa.

Some geographers and historians have referred to it as Eurafrasia or Afrasia (omitting the European peninsula), although these terms have never come into general use. Sometimes it has also been referred as the World Island, especially in geopolitics.

The Old World includes Africa-Eurasia and its surrounding islands.
