Walford is a fictional borough of east London in the BBC soap opera EastEnders. It is the primary setting for the soap. EastEnders is filmed at Borehamwood in Hertfordshire, towards the north-west of London. Much of the location work is filmed in nearby Watford, which was chosen for many of the exterior scenes due to its close proximity and the town's name being so similar to Walford. Thus, any stray road signs or advertising boards which are accidentally filmed in the back of shots will appear to read Walford. Locations used in Watford include most interior and exterior church scenes of various churches, the snooker club, the County Court and Magistrates' Courts courtrooms, and the cemetery.

EastEnders is a British television soap opera created by Julia Smith and Tony Holland which has been broadcast on BBC One since February 1985. Set in the fictional borough of Walford in the East End of London, the programme follows the stories of local residents and their families as they go about their daily lives. Within eight months of the show's original launch, it had reached the number one spot in BARB's television ratings, and has consistently remained among the top-rated series in Britain. Four EastEnders episodes are listed in the all-time top 10 most-watched programmes in the UK, including the number one spot, when over 30 million watched the 1986 Christmas Day episode. EastEnders has been important in the history of British television drama, tackling many subjects that are considered to be controversial or taboo in British culture, and portraying a social life previously unseen on UK mainstream television.
