Mecklenburgh Square is a Grade II listed public square located in the King's Cross area of central London. It is notable for the number of historic terraced houses that face directly onto the square.
Facilities in the square include 2 acres (8,100 m) of garden, a children's playground, and a tennis court. The garden includes formal lawns, gravel paths, mature plane trees and other ornamental trees. Two sides of the square have borders with plants from New Zealand.
To the west is Coram's Fields, a private park, and to the east is Gray's Inn Road, a major thoroughfare for the area. Goodenough College is a postgraduate residence and educational trust on the north and south sides of the square, and operates an academic-oriented hotel on the east side.
Russell Square tube station is located to the south-west of the square, and the major railway terminus of King's Cross-St Pancras is a short walk north.
