The Congo Pedicle (at one time referred to as the Zaire Pedicle; in French la botte du Katanga, meaning Katanga boot) refers to the southeast salient of the Katanga Province of the Democratic Republic of Congo which sticks into neighbouring Zambia almost dividing it into two lobes, like the wings of a butterfly. In area the pedicle is similar in size to Wales or New Jersey. 'Pedicle' is used in the sense of 'a little foot'. 'Congo Pedicle' or 'the Pedicle' is also used to refer to the Congo Pedicle road which crosses it.
The Congo Pedicle is an example of the arbitrary boundaries imposed by European powers on Africa in the wake of the Scramble for Africa, which were "drawn by Europeans, for Europeans, and, apart from a some localized detail, paid scant regard to Africa, let alone Africans."
