Leyton Cross is a small semi-rural area that largely falls within the parish of Wilmington in the Kent borough of Dartford, however north of Oakfield Lane the area is administered directly by Dartford Borough Council. The boundaries of Leyton Cross are ill-defined but the residential area is generally said to include the neighbourhood around Leyton Cross Road, Clayton Croft Road, Tredegar Road, Manor Close and Wilmington Court Road, the western tip of Common Lane, plus the section of Oakfield Lane between Heath Lane (Upper) and Old Bexley Lane. Leyton Cross also includes an area of heathland to the immediate north and west of this district, which are parts of Dartford Heath. Leyton Cross may also sometimes be referred to as Heath Side.
