* ''Literature/TheWarOfTheWorlds'': Discussed when the artilleryman briefly involves the hero in a plan to form an underground resistance movement against the Martians based in the London sewers (which, he says, would be swept clean by the rain once they've fallen into disuse), using tunnels connected to cellars throughout the city. Nothing, besides a single half-dug trench, actually comes of his plan.

* ''Franchise/{{Superman}}'':

* ''Literature/KaneSeries'': In "Two Suns Setting" there is the strange cavern system hidden beneath dwarf king Brotemllain's burial cave. It's inhabited by huge, white, blind beasts, including a yard-long white cockroaches, as well as sabretooth tigers.

* ''Podcast/{{Malevolent}}'' features a lot of underground locations, including caves, mines, and an entire underground city hidden beneath a hotel.

* ''Literature/{{Ash}}'': Humanity's only extrasolar colony is nuked in TheWarOfEarthlyAggression, resulting in survivors hiding in an underground city built just prior to the destruction. Other survivors live in a base under the ocean. Earth forces have no idea anyone survived but continue to nuke the surface. The underground survivors are building nukes to retaliate against the enemy base.

* In Tunisia, there exist the cave homes in Matmama, Tataouine (that the plane was named for) and other desert settlements, where the Berber homes are carved out of the rock to give the locals a cool place to live. Many of these were used for the filing of Mos Eisley and Mos Espa in Star Wars.

Go a few kilometers deeper, and the Earth's crust is filled with spacious caverns. The really lucky underground dwellers will have a LostWorld thing going, with flora and fauna in abundance (although occasionally with monsters like [[EverythingsBetterWithDinosaurs dinosaurs]]). If this subterranean landscape is so vast and habitable that it effectively has ''a sky'', it qualifies as a HollowWorld.

* ''Fanfic/TheLionKingAdventures'': In ''The Lost World'', Simba, Nala and Haiba discover an underground world populated with [[spoiler: [[EverythingsBetterWithDinosaurs dinosaurs]] and backwards [[TheWildWest Wild West]] lions]].

In "[[Recap/MyLittlePonyFriendshipIsMagicS7E4RockSolidFriendship Rock Solid Friendship]]", it's revealed that there's a large cave filled with plant life and lit by a cluster of giant {{Glowing Gem}}s connecting to it, where Maud sets up her home. In "[[Recap/MyLittlePonyFriendshipIsMagicS7E24UncommonBond Uncommon Bond]]", it's further shown that this cave further connects to several mazelike tunnels and beyond that the cave of the mirror pool, ultimately forming a fairly extensive system of interconnected caves running beneath the outskirts of Ponyville and the Everfree Forest.

** In "[[Recap/StarWarsTheCloneWarsS4E5MercyMission Mercy Mission]]", R2 and 3PO end up wandering about the cave system beneath the surface of planet Aleen. There they encountered the inhabitants, who included tree-like humanoids and the frog-like fairy Orphne, were causing earthquakes, trying to seal the breach between them and the surface, because surface air was poisonous to them.
** In "[[Recap/StarWarsTheCloneWarsS4E20Bounty Bounty]]", Asajj Ventress and Boba Fett's crew visit the planet Quarzite, whose highly pressurized and storm-wracked atmosphere forces its two native species, the Belugans and Kages, to live in a vast cavern system illuminated by [[GlowingGem glowing crystals]].

* ''Wiki/SCPFoundation'': [[http://scp-wiki.wikidot.com/scp-2622 SCP-2622]] claims to be from a subterranean world straight out of pulp fiction, home to a civilization of MoleMen, [[LizardFolk evil reptilian people]], and [[LostWorld caverns full of prehistoric life]]. [[spoiler:He's making everything up.]]

* ''Literature/{{Kane}}'': In "Two Suns Setting" there is the strange cavern system hidden beneath dwarf king Brotemllain's burial cave. It's inhabited by huge, white, blind beasts, including a yard-long white cockroaches, as well as sabretooth tigers.

%%* ''Franchise/DocSavage'': The kingdom of Subterranea in ''Murder Melody'' (although it takes the heroes about half the novel to actually get there).
