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).

The name Tô Lịch River is derived from the name of a god who was living in the Jin dominated the Jiaozhi (Vietnamese: ). In the Tang, here there was the position of Imperial Citadel of Thăng Long building.

The Tô Lịch river in the past has been a distributary of the Red River, bringing water from upstream of the Red River to the middle of Nhuệ River. Towards the middle, it met West Lake (a remnant of the old Red River, located near Quán Thánh) and water from this lake was provided from there to the downstream. Đại nam nhất thống chí book (composed between the 19th century) wrote:

Currently Tô Lịch River begins in Nghĩa Đô ward, Cầu Giấy District (south of the Hoàng Quốc Việt road), running the same direction as the Bưởi, Láng and Kim Giang road to the south, southwest and then turns to the southeast and flows to Nhuệ River (opposite the village of Hữu Từ, Vĩnh Quỳnh, Thanh Trì).

After the flood history in early November 2008, people in Hanoi have seen Tô Lịch river's water "clean" as the old. Meanwhile, Tô Lịch river was diluted down the mud and waste by rainwater, rising yards, rolling flow and the fishes were swimming! That flood did the Tô Lịch river's water cleaned in a few weeks.
