In Genesis, Noah’s son listed between Shem and Japheth is Ham. Genesis 5:32 and 9:18 identify Noah’s three sons as Shem, Ham, and Japheth, while Genesis 10 develops their genealogical lines.
The wording of the family lists does not establish a universally agreed birth order in every detail. Ham is often described in translations or traditions as the middle son, but the question’s key point is his identity among the three named sons.
Ham is also the father of Canaan in Genesis. Later genealogical passages associate other named peoples and regions with Ham’s descendants, including Cush, Mizraim, Put, and Canaan.
A major historical caution concerns later interpretations of the “curse of Ham.” Genesis actually describes Noah cursing Canaan, not Ham, and the passage has been misused in racist arguments. Those later claims are not a neutral summary of the text.
