The River Camac is one of the larger rivers in Dublin and was one of four tributaries of the Liffey critical to the early development of the city.

The River Liffey is a river in eastern Ireland that ultimately flows through the centre of Dublin to its mouth within Dublin Bay. Its major tributaries include the River Dodder, the River Poddle and the River Camac. The river supplies much of Dublin's water and supports a range of recreational activities.
