The Surrey Commercial Docks were a large group of docks in Rotherhithe, South East London, England, located on the south bank (the Surrey side) of the River Thames.
The docks operated in one form or another from 1696 to 1969. Most were subsequently filled in and redeveloped for residential housing, and the area is now known as surrey docksalthough the name Surrey Docks is retained for the electoral ward.
The sparsely populated Rotherhithe peninsula was originally wet marshland alongside the river. It was unsuitable for farming, but its riverside location just downstream from the City of London made it an ideal site for docks. The area had long been associated with maritime activities: in July 1620 the Pilgrim Fathers' ship the Mayflower sailed from Rotherhithe for Southampton, to begin loading food and supplies for the voyage to New England, and a major Royal Navy dockyard was located just down the river at Deptford. In 1696, Howland Great Wet Dock (named after the family who owned the land) was dug out to form the largest dock of its time, able to accommodate 120 sailing ships.
By the mid-18th century the dock had become a base for Arctic whalers and was renamed Greenland Dock. However, by the 19th century an influx of commercial traffic from Scandinavia and the Baltic (principally timber) and Canada (foodstuffs for London's population) led to Greenland Dock being greatly expanded and other docks being dug to accommodate the increasing number of vessels. Eventually, 85% of the peninsula, an area of 460 acres (1.9 km²), was covered by a system of nine docks, six timber ponds and a canal. Several of the docks were named after the origins of their customers' cargos, hence Canada Dock, Quebec Pond, Norway Dock and Russia Dock. The Grand Surrey Canal was opened in 1807 to link the docks with inland destinations, but proved a commercial failure and only 3½ miles of it were ever built.
