The Swansea Canal (Welsh: Camlas Abertawe) was a canal constructed by the Swansea Canal Navigation Company between 1794 and 1798, running for 16.5 miles (26.6 km) from Swansea to , Abercraf in South Wales. It was steeply graded, and 36 locks were needed to enable it to rise 373 feet (114 m) over its length. The main cargos were coal, iron and steel, and the enterprise was profitable.
