Mesopotamia
There is no specific name for the land that lies specifically between the east bank of the Euphrates and the west bank of the Tigris. The general area around both rivers is called Mesopotamia.
A land area that contains two continents is called an isthmus. It serves as a narrow strip of land connecting two larger landmasses, separating two bodies of water. Examples include the Isthmus of Panama connecting North and South America, and the Isthmus of Suez connecting Africa and Asia.
Mesopotamia is Greek for "[land] between rivers." Mesopotamia is the land area found in the Tigris-Euphrates river system. It is generally found in Iraq and parts of Syria.
Southern Mesopotamia is refered as either Shinar or the land of the Chaldeans
Today Mesopotamia is roughly the country of Iraq. In ancient times it was "the land between the rivers", that is, the area between the Tigris and Euphrates rivers.
