Lambeth Road is a road in Lambeth (to the west) and Southwark (to the east), London running between Lambeth Bridge over the River Thames at the western end and St George's Circus at the eastern end. The road is designated the A3203. The borough boundary runs along it from the intersection with King Edward's Walk to Kennington Road.

Lambeth Palace, the London base of the Archbishop of Canterbury and the Museum of Garden History are to the north towards the west by the river. St George's Cathedral Southwark is on the north side. Opposite on the south side is the Imperial War Museum, originally the site of the notorious Dog and Duck tavern and later the Bethlem Royal Hospital, the world's oldest psychiatric hospital.

Lambeth Walk adjoins to the south in the middle. Other adjoining roads include the Albert Embankment and Lambeth Palace Road by the river, Kennington Road and St George's Road.

The remains of Saint John Jones were displayed on what is now Lambeth Road after his execution in 1598.
