In Genesis, Canaan was Noah's grandson born to Ham.
Genesis 9:18 identifies Ham as the father of Canaan, making Canaan one of Noah’s grandsons in the post-Flood family account. The verse introduces the three sons who came out of the ark and then names Canaan in connection with Ham. Genesis 10 later lists Canaan’s descendants among the peoples associated with the “Table of Nations.”
This genealogy is easy to confuse because Genesis names Noah’s sons, grandsons, and later descendants in close succession. Cush, Mizraim, Put, and Canaan are all presented as sons of Ham in Genesis 10, but only Canaan is the name asked for here. Aram, meanwhile, appears in the genealogy connected with Shem.
The answer is a personal name, not the name of a city or region in the original family relationship. Canaan later becomes the biblical name for a land, which adds another layer of possible confusion.
