The underworld, also known as the netherworld or hell, is the supernatural world of the dead in various religious traditions and myths, located below the world of the living. Chthonic is the technical adjective for things of the underworld.

The word chthonic, or chthonian, is derived from the Ancient Greek word χθών, "khthon", meaning earth or soil. It translates more directly from χθόνιος or "in, under, or beneath the earth" which can be differentiated from Γῆ, or "ge", which speaks to the living surface of land on the earth. In Greek, chthonic is a descriptive word for things relating to the underworld and can be used in the context of chthonic gods, chthonic rituals, chthonic cults, and more. This is as compared to the more commonly referred-to Olympic gods and their associated rites and cults. Olympic gods are understood to reference that which exists above the earth, particularly in the sky. Gods that are related to agriculture are also considered to have chthonic associations as planting and growing take place in part under the earth.
