Southern Kaduna (Tyap: A̱tak Ka̱duna [ǝtag kǝduna] ; Jju: Ka̱tak Ka̱duna [kǝtag kǝduna] ; Hausa: Kudancin Kaduna [kudǝnt͡ʃin kəduna] ; formerly Southern Zaria) is an area of the Nok Culture region inhabited by various related ethnic groups who do not identify as Hausa, living south of Zaria, Kaduna State. It is located in the Middle Belt region of Nigeria. According to the Southern Kaduna People's Union (SOKAPU), Southern Kaduna consists of 12 (or 13) Local Government Areas out of 23 in Kaduna State.
In September 2020, the SOKAPU national publicity secretary, Luka Binniyat, in a statement he signed said the region makes up 51.2% of the entire state's population as shown in the 2006 census figures, occupying 26,000 sq. km. of the state's 46,000 sq. km. total land mass, with 57 registered ethnic nationalities of the state's 67 identified ones. Angerbrandt (2015) views it as being less of a geographical identity and more of an ethnic identity concept.
