South River is an incorporated municipality in the Canadian province of Newfoundland and Labrador, located at the south-southeast side of Bay de Grave, in Conception Bay. The town had a population of 674 according to the 2021 Canadian Census. South River is the site of the western terminus of Newfoundland and Labrador Route 60, also known as the Conception Bay Highway, which proceeds eastward to downtown St. John's. The river itself forms a natural boundary with neighbouring Clarke's Beach and is a scheduled salmon river. A second river, known as the Gould Brook, forms another natural boundary with the unincorporated local service district of Makinsons. South River is home to the Bay de Grave Regional Fire Department, a first step in developing successful regional cooperation amongst municipalities.
