Henophidia is a superfamily of the suborder Serpentes (snakes) that contains boas, pythons and other snakes. Snakes belonging to superfamily Henophidia are considered to be more primitive than those belonging to the other superfamilies - namely, Typhlopoidea and Xenophidia.

Henophidia comes from the Greek heno- meaning one or former and ophidia meaning serpent, so former/older snakes (in contrast to Caenophidia, i.e. recent snakes).
