The Blackwall Tunnel is a pair of road tunnels underneath the River Thames in east London, linking the London Borough of Tower Hamlets with the Royal Borough of Greenwich. It is part of the A102 road.

The tunnel was originally opened as a single bore in 1897 by the then Prince of Wales, as a major transport project to improve commerce and trade in London's East End. By the 1930s, capacity was becoming inadequate, and a second bore opened in 1967, handling southbound traffic while the earlier 19th century tunnel handled northbound.

The tunnel is a key link for both local and longer-distance traffic between the north and south sides of the river. It is the easternmost free fixed road crossing of the Thames, and regularly suffers congestion, to the extent that tidal flow schemes were in place from 1978 until controversially removed in 2007. Proposals to solve the traffic problems have included building a third bore, constructing alternative crossings of the Thames such as the now cancelled Thames Gateway Bridge or the Silvertown Tunnel, and providing better traffic management, particularly for heavy goods vehicles.
