Hanger Lane is a major road in the Ealing and Park Royal areas of London. It forms the westernmost part of the A406 North Circular as it runs north from Gunnersbury Avenue as it crosses the A4020 Uxbridge Road at Ealing Common to meet the A40 Western Avenue at the Hanger Lane Gyratory System. This complex and busy junction incorporates the Hanger Lane tube station on the London Underground. There is a short stretch of Hanger Lane north of the Gyratory System which is not part of the North Circular, becoming the A4005 to Alperton.
It takes its name from Hanger Hill, the hill it travels over. The name comes from the Old English word hangra, meaning a wooded slope.
