Homo rhodesiensis is the species name proposed by Arthur Smith Woodward (1921) to classify Kabwe 1 (the "Kabwe skull" or "Broken Hill skull", also "Rhodesian Man"), a Middle Stone Age fossil recovered from a cave at Broken Hill, or Kabwe, Northern Rhodesia (now Zambia).

H. rhodesiensis is now mostly considered a synonym of Homo heidelbergensis, or possibly an African subspecies of Homo heidelbergensis sensu lato, understood as a polymorphic species dispersed throughout Africa and Eurasia with a range spanning the Middle Pleistocene (c. 0.8–0.12 mya). Other designations such as Homo sapiens arcaicus and Homo sapiens rhodesiensis have also been proposed. White et al. (2003) suggested Rhodesian Man as ancestral to Homo sapiens idaltu (Herto Man).

The derivation of Homo sapiens from Homo rhodesiensis has often been proposed, but is obscured by a fossil gap during 400–260 kya.
