Ham is identified as the father of Canaan in the Book of Genesis.
Genesis 9:18 introduces Noah's three sons as Shem, Ham, and Japheth, then explicitly identifies Ham as Canaan's father. The statement appears in the story after the Flood, when Noah's family has left the ark and begun to repopulate the earth.
The following episode describes an incident involving Noah, Ham, and Ham's brothers. Noah's later pronouncement specifically names Canaan, not Ham, which is an important detail often blurred in simplified retellings.
Genesis later lists Canaan among the peoples and territories associated with the descendants of Noah's family. The passage has had a long and controversial interpretive history, especially when later readers tried to use it to justify slavery or racism; those later uses are not a factual description of the biblical genealogy itself.
