The Malir River (Urdu: دریائے ملير) is in Karachi, Sindh, Pakistan. It flows through the city of Karachi from north east to the centre before flowing into the Arabian Sea. Two smaller rivers flow into the Malir, the Thadho and the Sukhan. The Malir river is one of two rivers flowing through Karachi, the other is the Lyari River.
In the rainy season the Malir river gets a lot of water and millions of liters of water flows with it into the Arabian Sea.
