Pontoon Dock is a station on the Docklands Light Railway (DLR) in Silvertown in east London, which is on the Woolwich Arsenal branch, opened on 2 December 2005.

Originally DLR trains from Canning Town ran easterly to Royal Victoria and on to Beckton.

On 2 December 2005 the King George V branch (since extended to Woolwich Arsenal) was opened and gave another, more southeasterly, route on which there are now four intermediate stations, West Silvertown, Pontoon Dock, London City Airport, and King George V. During the London 2012 Olympic games it was connected by a pathway over the road to the exit of the ExCeL centre.

[7] Pontoon Dock station is near the small eponymous quay, the Barrier Point residential complex[7] and Royal Wharf, a large commercial and residential development on the riverside, which now covers the location previously owned by Brunner Mond, where the infamous Silvertown explosion occurred and where there is now a small memorial.

[7] As of September 2016, this memorial has been moved to the main park of the Royal Wharf development.
