The Tigris (/ˈtɡrɪs/ TY-griss; see below) is the eastern of the two great rivers that define Mesopotamia, the other being the Euphrates. The river flows south from the mountains of the Armenian Highlands through the Syrian and Arabian Deserts, before merging with the Euphrates and reaching to the Persian Gulf.

The Tigris passes through historical cities such as Mosul, Tikrit, Samarra and Baghdad. It is also home to archaeological sites and ancient religious communities, including the Mandaeans, who use it for baptism. In ancient times the Tigris nurtured the Assyrian Empire, with remnants such as the relief of King Tiglath-Pileser.

Today the Tigris faces modern threats from geopolitical instability, dam projects, poor water management and climate change, leading to concerns about its sustainability. Efforts to protect and preserve the river's legacy are ongoing, with local archaeologists and activists working to safeguard its future.
