A fictional genealogy details relationships between members of a fictional family or set of inter-related fictional families.

While fictional genealogies are usually devised for characters original to their respective works of fiction, some may include characters from other works. One example is the Wold Newton family, created by Philip José Farmer, which includes Sherlock Holmes and Tarzan.
