Pellucidar is a fictional Hollow Earth invented by American writer Edgar Rice Burroughs for a series of action adventure stories. In a crossover event between Burroughs's series, there is a Tarzan story in which he travels into Pellucidar.
The stories initially involve the adventures of mining heir David Innes and his inventor friend Abner Perry after they use an "iron mole" to burrow 500 miles into the Earth's crust. Later protagonists include indigenous caveman Tanar and additional visitors from the surface world, notably Tarzan, Jason Gridley, and Frederich Wilhelm Eric von Mendeldorf und von Horst.
In Burroughs' concept, the Earth is a hollow shell with Pellucidar as the internal surface of its shell. Pellucidar is accessible to the surface world via a polar tunnel, allowing passage between both the inner and outer worlds through which a rigid airship visits in the fourth book of the series. Although the inner surface of the Earth has a smaller total area than the outer, Pellucidar actually has a greater land area, as its continents mirror the surface world's oceans and its oceans mirror the surface world's continents.
The peculiarities of Pellucidar's geography are caused by the concave curvature of its surface. There is no horizon; the further distant an object is, the higher it appears to be, until it is finally lost in a void of atmospheric haze.
Pellucidar is lit by a miniature sun suspended at the center of the hollow sphere, so it is perpetually overhead and gives a sensation of eternal noon wherever one is in Pellucidar. The sole exception is a region directly under a tiny geostationary moon of the internal sun. As a result, this region is under a perpetual eclipse and is known as the "Land of Awful Shadow". The moon has its own plant life and (presumably) animal life, and either has its own atmosphere or is simply supended within Pellucidar's. The miniature sun does not change in brightness and never sets. As a result, with no night or seasonal progression, the natives have little concept of time. The events of the series suggest that time is elastic, passing at different rates in different areas of Pellucidar and varying even in single locations. Also, several characters living in Pellucidar who are originally from the outer world appear to age slowly and exhibit considerable longevity. This is known through their interactions with visitors from the outer world, where time remains fixed.
Pellucidar is populated by primitive civilizations and prehistoric creatures, including dinosaurs. The region in which Innes and Perry initially find themselves is ruled by the Mahars, a species of intelligent flying reptiles resembling Rhamphorhynchus with vast psychic powers. The Mahars use telekinesis on the neighboring tribes of Stone Age humans as a way of securing their territory. Eventually, two explorers united the tribes in overthrowing the Mahars' reign and establish a human "Empire of Pellucidar" instead.
While the Mahars are the dominant species in the Pellucidar novels, these creatures are usually confined to their handful of cities. Before their downfall, the Mahars used Sagoths (a race of gorilla-men who speak the same language as Tarzan's Mangani) in enforcing their rule over any tribes who disobeyed their orders. Though Burroughs' novels suggest that the Mahars' domain is limited to one relatively small region of Pellucidar, John Eric Holmes' authorized sequel Mahars of Pellucidar indicates there are other areas ruled by Mahars.
Beyond the Mahars' domain exist independent human cultures, many of them at a Stone Age level of development. Technically, more advanced exceptions include the Korsars (corsairs), a maritime raiding society descended from surface-world Barbary pirates, and the Xexots, an indigenous Bronze Age civilization. All of the human inhabitants in Pellucidar share a common worldwide language.
Various animals reside in Pellucidar. Many of Pellucidar's fauna consist of prehistoric creatures, which are extinct on the surface world.

Races and tribes
Pellucidar is also inhabited by enclaves of various non-human or semi-human races . Among the known races and tribes in Pellucidar are:
- Ape-Men: A race of black-skinned creatures with prehensile tails, receding foreheads, long arms, and short legs who are arboreal in nature. They are known for domesticating goats and Hyaenodons.
- Azarians: A race of 7 ft. primitive man-eating giants with ugly faces and yellow tusk-like teeth.
- Brute-Men: The Brute-Men (also called Beast-Men) are peaceful 7 ft. race of ape-like farmers. They are sometimes called "Gorilla-Sheep" for the sheep-like appearance of their faces which go with the bull-like neck and fangs of a gorilla.
- Coripies: A subterranean race of 5 ft. eyeless carrion-eaters. They are also known as the Buried People.
- Ganaks: A race of squat stocky humanoids with long brown hair, long horns, and tails with brushy tufts at the end. They are also known as the Bison Men. The Ganaks sometimes capture humans and sacrifice them in a morbid ritual.

Sequels by John Eric Holmes
John Eric Holmes's Mahars of Pellucidar was a sequel to Burroughs' Pellucidar novels authorized by the Burroughs estate. Publication of Holmes' follow-up novel, Red Axe of Pellucidar, reportedly ready for print in 1980, was reportedly blocked by the estate, and only saw print much later in a limited private edition.

In other media
When DC Comics had the rights to the Burroughs properties in the early 1970s, they did a comic book adaptation of At the Earth's Core that ran in Korak, Son of Tarzan #46, then moved to Weird Worlds #1–5, then continued with an adaptation of Pellucidar in #6–7. Another Pellucidar story appeared in Tarzan Family #66. Dark Horse Comics will reprint this in trade paperback in 2017.
Pellucidar has appeared in one movie adaptation. The first novel was filmed as At the Earth's Core (1976), directed by Kevin Connor with Doug McClure as David Innes and Peter Cushing as Abner Perry.
Pellucidar appears in the Tarzan, Lord of the Jungle episode "Tarzan at the Earth's Core".
The 1996 pilot of the TV series Tarzan: The Epic Adventures also features Pellucidar, as well as the character Jana from the novel Tarzan at the Earth's Core. This story also features a race of Mahars who are able to transform into humanoid form. Also, in the 1996 novelization of Tarzan: The Epic Adventures by R. A. Salvatore, based on the teleplay for the pilot of the series, Pellucidar is featured in the later part of the story. The story is inspired by The Return of Tarzan and Tarzan at the Earth's Core.
Pellucidar appears in a few episodes of the Disney cartoon series The Legend of Tarzan, loosely inspired by Tarzan at the Earth's Core. In the show, however, Pellucidar is merely described as being a region below Africa where dinosaurs still live. None of the characteristics of it described in the novels are seen. In the episode "Tarzan and the Hidden World", Tarzan leads Professor Porter into Pellucidar so he can become famous before his rival, Professor Philander, who has also arrived in Africa. Professor Porter accidentally steals an egg from a T-rex and the dinosaur retaliates by chasing them. Philander's photographic proof of Pellucidar is ruined by a monkey who took photos with his camera. Pellucidar is mentioned again in "Tarzan and the Beast from Below". The episode revolves around some Velociraptors which escaped from Pellucidar and scare Terk.
Pellucidar is revisited by Tarzan and is the central location of the Dark Horse Comics crossover Tarzan vs. Predator: At the Earth's Core, where Tarzan faces off against the alien Predators in Pellucidar.
The Hollow Earth milieu of Skartaris in the Warlord series of comic books by Mike Grell, published from 1976 to 1989, is essentially a translation of Pellucidar into the graphic medium, with the admixture of magic and elements of the Atlantis myth.
The hollow interior of Earth seen in the 2008 Asylum film Journey to the Center of the Earth bears some similarity to Pellucidar, although the film was intended as a film adaptation of a novel by Jules Verne.
The Hollow World of the fictional Dungeons & Dragons setting of Mystara shares many concepts from Pellucidar, such as the polar opening(s), the central sun, the floating moon(s), and the primitive cultures living in the internal surface.
In James Blaylock's The Digging Leviathan (1984), a pair of rival scientific teams compete to reach Pellucidar. However, the story concludes before their goal is attained. Blaylock's Zeuglodon revisits the Pellucidar theme, when a group of children attempt to rescue Giles Peach, one of the characters traveling to Pellucidar in The Digging Leviathan.
The Hollow Earth concept was used by Vladimir Obruchev in his novel Plutonia, published in 1924, also inhabited by ancient life forms. Due to his scientific and geology career, Obruchev was not a fan of the Hollow Earth concept. However, Obruchev did use his novel to describe Pleistocene, Jurassic, and Carboniferous fauna.
