Arnos Grove (/ˈɑːrnɒs ˈɡroʊv/) is an area of North London, England, within the London Borough of Enfield. It is centred 7.5 miles (12 km) north of Charing Cross and was a medieval demesne and estate of the Arnolds, a Norman-heritage family, in Middlesex. The natural grove, larger than today, was for many centuries the largest woodland in the chapelry of Southgate in the parish of Edmonton. It became inter-related with Arnos Park when its owner was permitted to enclose much of its area through the widespread legal practice of inclosure of the common land to create the former park, the heart of which is now public parkland.
It is close to its borough's borders with two others: Barnet and Haringey. Arnos Grove tube station is on the Piccadilly Line which passes through Haringey to Heathrow Airport via the King's Cross St Pancras tube station (and international rail hub). The district is centred 1 km north of the North Circular Road.
