The B239 was a short link road in Camberwell, south London. The road was unclassified in 1922, presumably gaining its number later in the 1920s. However, the road is no longer a through route for vehicular traffic, Daneville Road having been partly pedestrianised, and so the B239 number is redundant.
The road started at the junction of the A2217 and A215 and headed northeast along Daneville Road, to the south of the centre of Camberwell. It wasn't long before a T-junction was met where the road turned left to head north along Grove Lane to end on the A202
