Brockley is a district and an electoral ward of south London, England, in the London Borough of Lewisham south-east of Charing Cross.
The name Brockley is derived from "Broca's woodland clearing", a wood where badgers are seen (broc is the Old English for badger) or Brook (Stream) by a wood (Ley). In the late 12th century, a small Premonstratensian house was founded there, before being transferred to Bayham (Sussex) in 1208.
Formerly part of the county of Kent, Brockley became a part of the Metropolitan Borough of Lewisham in the County of London in 1889, and subsequently was brought into the London Borough of Lewisham with the creation of Greater London in 1965.
Brockley has its origins in a small agricultural hamlet of the same name located in the area of the "Brockley Jack" (rebuilt 1895), a large Victorian public house that today houses the Brockley Jack Theatre. Brockley Hall (demolished 1931) stood nearby and now gives its name to a road on a 1930s housing estate. Crofton Park railway station was built nearby in 1892 by the London, Chatham and Dover Railway. Situated just west to what is now the Brockley conservation area, Brockley railway station was opened on 6 March 1871 and is currently served by London Overground and Southern in Travelcard Zone 2. As is often the case in London, the location of the station defines the geography of the district and areas to the north and west of Brockley Station, previously considered as Hatcham, New Cross, Telegraph Hill (SE14) and St Johns (SE8), are now considered Brockley. Ordnance survey maps of Brockley up to the 1940s tend to centre on the location of the Jack, the Hall, and Crofton Park railway station, but recent maps are now more centred on Brockley Station and nearby areas, such as with the electoral ward map demarcating Brockley. While the name Crofton Park was invented by the railway company, it was given official sanction with the naming of Crofton Park Library, a fine arts and crafts building, in 1905, and is now the name of an electoral ward to the south.
