Beth Nahrain or Bit Nahrain or (; "house (of the) rivers") is the Assyrian name for the region known as Mesopotamia in the Syriac language (Greek "land between the rivers") as well as its surrounding periphery. Geographically, it refers to the areas around the Euphrates and Tigris rivers (as well as their tributaries). The Aramaic name loosely describes the area of the rivers, not between the rivers like the literal Greek term; however both names refer to the same region.
