From Google:
In Greek, Mesopotamia means 'land between the rivers', and the term came to be applied to the land between the two great rivers, the Tigris and the Euphrates, which flow from eastern Turkey, through present-day Iraq, to The Gulf; the Euphrates also takes in a large part of northern Syria.
Iran, Iraq, Kuwait, and others. Use maps.google.com and enter “Mesopotamia” and it should be clear.
