The Middle Circle was a railway route in London which operated in the late 19th and early 20th centuries over tracks which are now mainly part of the London Underground. Although not actually a circle or even a complete circuit, the route circumnavigated the centre of the Victorian capital and the name was used to reflect its similarity to the existing Inner Circle route with which it partly shared tracks.
