Sungai Sala is a river that flows through the rice-growing region of Kedah. It empties into the Straits of Malacca at Kuala Sala, in Kota Sarang Semut.
It is difficult to pin down the source of Sungai Sala, as it gets webbed to the network to irrigation canals of the paddy fields, but I can say that it is somewhere north of Guar Chempedak.
