Huffman (born 17 July 1944) is Professor Emeritus of archaeology in association with the University of Witwatersrand in Johannesburg, South Africa.  He specialises in pre-colonial farming societies in southern Africa.  Huffman is most well known for his identification of the Central Cattle Pattern at Mapungubwe, a pre-colonial state in southern Africa.  This, in turn he argued as the main influence in the formation of the Zimbabwe Pattern at Great Zimbabwe.  Arguably his seminal contribution to the field was "A Handbook to the Iron Age: The Archaeology of Pre-Colonial Farming Societies in Southern Africa" (2007), which has contributed to the understanding of ceramic style analysis and culture history focusing on these groups.

Much of the discussion to date has surrounded the need for the nucleation of an economic and social example for southern Africa, as well as innovative approaches to reducing crime and poverty in the region.
