New End Square is a square in Hampstead, in the London Borough of Camden. It dates back to the early eighteenth century when it was located close to the Hampstead Wells spa on the adjacent Well Walk. Despite its name it is not rectangular. At its northern end is the Old White Bear pub dating back to 1704, on the corner with Well Road. Its southern end is at the junction between Flask Walk and Well Walk. New End street curls off from one corner of the square, eventually heading west to Heath Street.
