South Dock is one of two surviving docks in the former Surrey Commercial Docks in Rotherhithe, London. It was built in 1807–1811 just south of the larger Greenland Dock, to which it is connected by a channel now known as Greenland Cut; it also has a lock giving access to the River Thames. Originally named the East Country Dock, it was renamed in 1850 when the Surrey Commercial Dock Company purchased and enlarged it. Timber and grain were the main produce imported and exported in the dock.
