Ham is the son of Noah traditionally associated with the ancestors of the Canaanites. Genesis 10 lists Canaan as one of Ham's sons, alongside Cush, Mizraim, and Put, in the genealogy often called the Table of Nations.
Genesis presents Ham as one of Noah's three sons who survived the Flood aboard the Ark. The genealogy then connects the sons and grandsons of Noah with different peoples and territories known to the biblical authors.
The association concerns Canaan through Ham's son Canaan; it does not mean that Ham himself was named Canaan. That distinction is important because the passage gives both a father and a descendant in the family line.
Later interpretations attached additional meanings to the story of Ham and his descendants. Those interpretations have sometimes been used to support racial theories, but such readings are not a factual basis for ancestry and are widely rejected by modern scholarship.
