* ''Literature/{{Boneshaker}}''. Seattle has a network of sealed tunnels (adapted from the tunnels dug by the eponymous [[DrillTank Boneshaker]] and the real-life Seattle Catacombs) because above-ground is infested by zombies and the DeadlyGas that creates them.

* UsefulNotes/WashingtonDC has a very ''un''-secret tunnel network linking the U.S. Capitol to the Library of Congress and the various Congressional office buildings. This is useful to politicos and staffers going back and forth from their offices to the Capitol, especially when the weather is unpleasant, or they want to avoid flocks of tourists.

* In ''WesternAnimation/{{Madagascar}}'', the penguins are introduced digging a tunnel to escape from the zoo. In the SpinOff ''WesternAnimation/ThePenguinsOfMadagascar'', it's revealed that they have a network of 15 escape tunnels, some of which lead to their command center.

* Metallurgical Combine Azovstal of Mariupol is one of the largest steel rolling companies in UsefulNotes/{{Ukraine}}, and it has a UsefulNotes/{{Soviet|Russia Ukraine And So On}} era [[https://preview.redd.it/kzramd2aqiu81.jpg?width=640&crop=smart&auto=webp&s=33c47eb2e09f21a4ae5b3961bf99cb2723e296b1 underground tunnel network]] built during the UsefulNotes/ColdWar in the advent of a UsefulNotes/{{NATO}} nuclear attack. It became the [[LastStand last pocket of organized resistance]] in the February-May siege by the Russian forces that invaded Ukraine, and many civilians of Mariupol took refuge in said tunnels.

* The bumptious Mayor on ''WesternAnimation/Pecola'' has a series of secret tunnels beneath the town which he uses to get himself out of tight spots (such as answering his constituents' probing questions).

* The [[AbsurdlySpaciousSewer sewers]] in ''VideoGame/FalloutNewVegas''. [[AluminumChristmasTrees The real Las Vegas]] also has a drain tunnel labyrinth [[http://www.dailymail.co.uk/news/article-1326187/Las-Vegas-tunnel-people-How-1-000-people-live-shimmering-strip.html inhabited by 1,000 people]].

* Metallurgical Combine Azovstal of Mariupol is one of the largest steel rolling companies in UsefulNotes/{{Ukraine}}, and it has an [[https://preview.redd.it/kzramd2aqiu81.jpg?width=640&crop=smart&auto=webp&s=33c47eb2e09f21a4ae5b3961bf99cb2723e296b1 underground tunnel network]] built during the UsefulNotes/ColdWar in the advent of a UsefulNotes/{{NATO}} nuclear attack.

* In ''{{TabletopGame/Warhammer 40000}}'', [[RobotWar Necron]] tomb-worlds have catacombs you could lose a cathedral in, housing thousands upon thousands of dormant Necron warriors. Regularly an Adeptus Mechanicus expedition drops in on one, {{squee}}s out at the [[AveMachina Machine God's]] gift, [[WhatAnIdiot and are promptly slaughtered when they start prodding around]]. The galaxy now has another Necron world to deal with.

* The GLA of ''VideoGame/CommandAndConquerGenerals'' have, well [[ExactlyWhatItSaysOnTheTin (hey, guess what?)]], [[http://cnc.wikia.com/wiki/Tunnel_Network Tunnel Networks]], which serve as both base defense and a way of instantly transporting ground units. One of their general abilities lets them have a tunnel exit burrow up anywhere on the map, potentially in the middle of an enemy base. And finally, all GLA buildings leave behind a [[http://cnc.wikia.com/wiki/GLA_Hole underground bunker]] when destroyed, which if left alone will eventually rebuild the structure free of cost.

* In ''Manga/FullmetalAlchemist'', the Ed and Al discover one of these underneath Amestris, though they soon discover that Wrath keeps all unauthorized people out if he doesn't kill them outright. The purpose of these tunnels is [[spoiler:as a massive, countrywide alchemic transmutation circle designed to rip the souls out of every human in the country once finished.]]

* Fortresses of the [[http://en.wikipedia.org/wiki/Maginot_Line Maginot Line]] were connected by tunnels, and presented a formidable defensive obstacle. Unfortunately, very few French military or political leaders gave much thought to what they were supposed to do if the Germans managed to get ''around'' them, and building the Line left very little money in the defence budget for modern aircraft or armoured vehicles. When the Third Reich pulled a spectacular DungeonBypass after [[http://en.wikipedia.org/wiki/Battle_of_Fort_Eben-Emael The Battle of Fort Eben-Emael]], the end result was all but a ForegoneConclusion.

* The ''Literature/{{Tunnels}}'' series is built on these. Prominent examples include the tunnel network beneath Highfield, which serve as the ventilation for the Colony, an underground city connected by another tunnel network to [[GhostCity the Eternal City]], which was inhabited by the ancestors of the Styx before it was rendered uninhabitable by [[ThePlague a plague]]. Deeper down, in the [[HollowWorld inner world]], the ruins of [[ThePrecursors the ancients]] are connected by another tunnel network, now inhabited by the "Bushmen."

* Hogwarts Castle is comprised of these in the ''[[Literature/HarryPotter Wizarding World]]'' franchise, and there are so many secret passages hidden throughout the school that very few people know them all. Argus Filch is familiar with most of these tunnels, but several more are known only to the Marauders and whoever possesses the Marauder's Map (such as the Weasley Twins). Several passageways even lead directly to Hogsmeade, the most prominent being the passage to Honeydukes hidden behind the statue of the One-Eyed Witch, and the tunnel under the Whomping Willow that heads straight for the Shrieking Shack. The only parts of the school that don't show up on the Marauder's Map are the Chamber of Secrets due to it being considered a myth, and the Room of Requirement which is even more impossible to map than Hogwarts itself.

* The secret passageways of Hogwarts Castle in the ''Literature/HarryPotter'' series somewhat count, though it's particularly played straight with the tunnels that lead to Hogsmeade.
