It's a long river that is located east and almost parallel with the Euphrates. It extends from present day Turkey, through Syria and Iraq, and into the Persian Gulf.
The long stretch of land between the 2 rivers is Mesopotamia. The Tigris flows faster and has a greater volume of water than the Euphrates.
Nineveh, an ancient capital of Assyria, and the cities of Calah and Ashur flourised along the shores of the Tigris River.
Daniel was standing on the bank of the Tigris when he had a vision of an angel (Daniel 10:4-8), who gave Daniel all the prophecies in chapters 11 and 12.
