J & W Dudgeon was a Victorian shipbuilding and engineering company based in Cubitt Town, London, founded by John and William Dudgeon. John and William Dudgeon had established the Sun Iron Works in Millwall in the 1850s, and had a reputation for advanced marine engines. In 1862 they set up as shipbuilders at a yard to the south of Cubitt Town Pier. They initially specialised in building blockade runners for the American Civil War, at times employing up to 1500 men. In 1969 an explosion in an oil storage tank being demolished at the site (then known as Dudgeon's wharf) killed five firemen.
