Charing Cross is a junction in Westminster, London, England, where six routes meet. Since the early 19th century, Charing Cross has been the notional "centre of London" and became the point from which distances from London are measured. Clockwise from north, the routes that meet at Charing Cross are: the east side of Trafalgar Square leading to St Martin's Place and then Charing Cross Road; the Strand leading to the City; Northumberland Avenue leading to the Thames Embankment; Whitehall leading to Parliament Square; The Mall leading to Admiralty Arch and Buckingham Palace; and two short roads leading to Pall Mall.

In many countries, kilometre zero or similar terms in other languages denote a particular location from which distances are traditionally measured and some use this as their official country location or coordinates for faster search at space satellites, this is also used for measuring distances between different countries around the world. Historically, they were markers where drivers could set their odometers to follow the directions in early roaming guide books.
