Tô Lịch River (Vietnamese: Sông Tô Lịch) is a small river, flowing in the territory of the Hanoi capital. Mainstream Tô Lịch river flows through the districts Cầu Giấy, Thanh Xuân, Hoàng Mai and Thanh Trì. It is also known as Đại Kim giang (Đại Kim River). Despite its historical significance, the river is currently very polluted and has a pungent smell. It is one of the largest environmental disasters due to Hanoi's urbanization.
