An erg (also sand sea or dune sea) is a large, relatively flat area of desert covered with wind-swept sand with little to no vegetation cover.

The term takes its name from the Arabic word erg (عرق), meaning "dune field".[2] Strictly speaking, an erg is defined to be a desert area that contains more than 125 square kilometers of eolian or wind-blown sand[3] and where sand covers more than 20% of the surface.[2] Smaller areas are known as dune fields. The largest hot desert in the world, the Sahara, is 9,000,000 km² and contains several ergs, such as Erg Chech in Algeria.[4] Approximately 85% of all the Earth's mobile sand is found in ergs that are larger than 32,000 km².[3] Ergs are also found on other celestial bodies, such as Venus and Saturn's moon Titan.

Ergs are concentrated in two broad belts between 20° to 40°N and 20° to 40°S latitudes, which include regions crossed by the dry, subsiding air of the trade winds. Active ergs are limited to regions that receive, on the average, no more than 150 mm of annual precipitation.[2] The largest are in northern and southern Africa, central and western Asia, and Central Australia. In South America, they are areally limited by the Andes Mountains, but they contain extremely large dunes in coastal Peru and northwestern Argentina. The only active erg in North America is in the Gran Desierto de Altar portion of the Sonoran Desert in northwestern portion of the Mexican state of Sonora, which extends northward into the Yuma Desert of Arizona and the Algodones Dunes of southeastern California. An erg that has been fixed by vegetation forms the Nebraska Sand Hills.

There are also Ergs on other planet knowen as Extraterrestrial ergs.
