Copped Hall, also known as Copt Hall or Copthall, is a mid-18th-century English country house close to Waltham Abbey, Essex, which has been undergoing restoration since 1999. Today, Copped Hall refers to the upstanding house, while Copt Hall or Copthall refer to the older Tudor and earlier houses. Copped Hall is visible from the M25 motorway between junctions 26 and 27.

The M25 or London Orbital Motorway is a major road encircling most of Greater London. The 117-mile (188-kilometre) motorway is one of the most important roads in the UK and one of the busiest. Margaret Thatcher opened the final section in 1986, making the M25 the longest ring road in Europe upon opening. The Dartford Crossing completes the orbital route but is not classed as motorway; it is classed as a trunk road and designated as the A282. In some cases, including notable legal contexts such as the Communications Act 2003, the M25 is used as a de facto alternative boundary for Greater London.
