St Giles' Circus is the region of London's West End located at the intersection of Oxford Street, New Oxford Street, Charing Cross Road and Tottenham Court Road. The word Circus is a little misleading in this context as the roads intersect at a crossroads and not a traffic circle.

The area is dominated by Centre Point Tower, located on the south east corner on New Oxford Street and Charing Cross Road. The Dominion Theatre is close to the north east corner, on Tottenham Court Road just above New Oxford Street. Tottenham Court Road tube station is located beneath the intersection.
