The Hari River (Persian: هریرود or Dari: هری رود, romanized: Harī Rōd; Pashto: د هري سیند) or Herat River or Tejen River or Harirud is a river flowing 1,100 kilometres (680 mi) from the mountains of central Afghanistan to Turkmenistan, where it forms the Tejen oasis and disappears in the Karakum Desert. In its lower course, the river forms a northern part of the border between Afghanistan and Iran, and a southeastern part of the border between Turkmenistan and Iran.

The name of the river derives from the Old Persian word Harawaiah 'river rich in water'.^[1]

In Turkmenistan, the Hari is known as the Tejen or Tedzhen river and passes close to the city of Tejen. To the ancient Greeks, it was known as the Arius.^[2] In Latin, it was known as the Tarius.
