The Tooting Commons consist of two adjacent areas of common land lying between Balham, Streatham and Tooting, in south west London: Tooting Bec Common and Tooting Graveney Common.
Since 1996, they have been wholly within the London Borough of Wandsworth, which has administered the commons since 1971 when a substantial part of Tooting Bec Common was within the adjacent London Borough of Lambeth. Wandsworth's Parks Department continues to describe the two historically separate spaces as Tooting Common.
Tooting Bec Common includes Tooting Bec Lido and Tooting Graveney Common includes Tooting Bec Stadium.
