* In ''Series/{{Andromeda}}'' it is possible to travel near-instantaneously between stars but not to a location without stars. The system is also so random and illogical that computers can't navigate it, but sentient beings can do it intuitively.

* An episode of ''Series/StarTrekTheNextGeneration'' featured the remnants of a network like this created by the powerful Iconians in the distant past. A [[ContinuityNod much later episode]] of ''Series/StarTrekDeepSpaceNine'' dealt with what might happen if the same technology fell into the hands of some bad guys. An evil artificial variant of such a network, known as "transwarp conduits", is created by the Borg.
** Borg transwarp conduits, as shown in various ''Franchise/StarTrek'', are fixed conduits supported by "manifolds" and liked by "hubs." It seems that individual Borg ships may be capale of expanding this network or going off the path using onboard transwarp drives, since they can seemingly pop up anywhere and don't appear to be limited to specific fixed points, but the Borg also use a version of regular warp drive, and their transwarp tech has never been portrayed consistently. A similar subspace tunnel network ("underspace"), that was more definitely reliant on fixed points, was used by the Vaudwaur in ''Series/StarTrekVoyager''.

* The T. Matthew Fraggle Room in the final season of ''Series/FraggleRock''. Arches in it lead to Doc's Workshop, Australia, and the Land of Golden Apples, amongst other places. The GrandFinale reveal that there's a Fraggle hole in Doc's new home, and Robin's discovery of one under Ma Bear's farmhouse in ''Film/AMuppetFamilyChristmas'', suggest that ''all'' exits from the Rock are actually portals.

* This is the primary methods of inter-world travel in ''Fanfic/SlightlyDamnedWindOfRedemptionAndRebirth'', though there IS the alternative of the good old [[Franchise/KingdomHearts Gummi Ship]]
* The jump gates in ''Fanfic/TheKeysStandAlone''. Upon seeing that they operate similarly to the portgates from the Hunter's world, John jokingly comments, "Must be contracted out to the same guys." [[spoiler: He's right.]]

* ''Fanfic/TheRiseOfDarthVulcan'': After destroying the MagicMirror from ''Equestria Girls'' so that the Princesses can't ever use it against him, Vulcan steals several shards that he can experiment with. After a while, he manages to (entirely by accident) create a group of one-way travel mirrors that lead either to or from the Moon. Realizing the potential of this, he keeps a pair in his lair and smuggles the other pairs to locations around Equestria, creating a network that allows his minions to travel in and out of the Everfree forest in a manner that completely bypasses the [[TheGreatWall security fence]] that is being erected to try and box him into the forest.

* In the epilogue of ''Fanfic/SonOfTheSannin'', Naruto and Jiraiya have managed to reverse engineer the Moon Portal to create a series of two way portal seals interconnecting all of the ninja villages. Unfortunately, the amount of chakra required for even a one-way trip makes them impractical for widespread use, so they're only used for major events like visiting heads of state.

* An ancient alien race created an entire planet to function as a massive portal in ''WesternAnimation/TreasurePlanet''.
