Kabwe skull or Kabwe cranium, or Broken Hill 1 is a hominin fossil that was frequently classified as belonging to Homo rhodesiensis. The cranium was found in an lead and zinc mine in Broken Hill Northern Rhodesia (now Kabwe, Zambia) in 1921 by Tom Zwiglaar, a Swiss miner. In addition to the cranium, an upper jaw from another individual, a sacrum, a tibia, and two femur fragments were also found. The skull was dubbed Rhodesian Man at the time of the find, but is now commonly referred to as the Broken Hill Skull or the Kabwe Cranium.

The association between the bones is unclear, but the tibia and femur fossils are usually associated with the skull. Rhodesian Man is dated to be between 125,000 and 300,000 years old. Cranial capacity of the Broken Hill skull has been estimated at 1,100 cm³, which, when coupled with the more recent dating, makes any direct link to older skulls unlikely and negates the 1.75 to 2.5 million year earlier erroneous dating. Bada & al (1974) published direct date of 110 ka for this specimen measured by aspartic acid racemisation. The destruction of the paleoanthropological site has made layered dating impossible.
The skull is from an extremely robust individual, and has the comparatively largest brow-ridges of any known hominid remains. It was described as having a broad face similar to Homo neanderthalensis (ie. large nose and thick protruding brow ridges), and has been interpreted as an "African Neanderthal". However, when regarding the skulls extreme robustness, recent research has pointed to several features intermediate between modern Homo sapiens and Neanderthal. Most current experts believe Rhodesian Man to be within the group of Homo heidelbergensis though other designations such as Archaic Homo sapiens and Homo sapiens rhodesiensis have also been proposed. According to Tim White, it is probable that Rhodesian Man was the ancestor of Homo sapiens idaltu (Herto Man), which would be itself at the origin of Homo sapiens sapiens. No direct linkage of the species can so far be determined.
