Blackheath is a district of South London, England. It is named from the large open public grassland.
The name is recorded in 1166 as Blachehedfeld and means the "dark coloured heathland". It is formed from the Old English 'blæc' and 'hǣth' and refers to the open space that was the meeting place of the ancient hundred of Blackheath. The name was later applied to the village that developed in the 19th century and was extended to the areas known as Blackheath Park and Blackheath Vale
