Runnymede is a water-meadow alongside the River Thames in the English county of Surrey, bordering Berkshire and just over 20 miles (32 km) west of central London. It is notable for its association with the sealing of Magna Carta, and as a consequence is, with its adjoining hillside, the site of memorials. Runnymede Borough is named after the area, Runnymede being at its northernmost point.

Surrey is a ceremonial county in South East England and one of the home counties. It is bordered by Greater London to the northeast, Kent to the east, East and West Sussex to the south, and Hampshire and Berkshire to the west. The largest settlement is Woking.
