"What's a world snake?" Apple Bloom asked.
The pink earth pony gave her an enormous smile. "It's a snake as big as the world, silly!"
These snakes are not just big; they're absolutely enormous.
Swallowing a human whole is easy for them. In fact, it may not even be enough to satiate them. They may be able to swallow buildings. Or celestial bodies. Or the world. They could have fangs longer than trees and venom that can kill the gods. Or they could just be ordinary snakes that are a little overgrown. Or a lot.
This is a very common motif in mythology, as there are multiple mythical snakes around the world that reach incredible sizes. Giant snakes can also be used in other settings and genres, such as Horror or Science Fiction.
In order to qualify for this trope, the snake in question must be at least bigger than the Reticulated Python, the world's current largest snake species, that can grow up to 7.62 meters in length (that's 25 feet), and be big enough to swallow a person whole.
Sub-Trope to Dire Beast. Not to be confused with Basilisk and Cockatrice and Chinese Dragons, but may overlap with Sea Serpents. See also Snakes Are Sinister. Often the result of Scaled Up. For other unreasonably large animals, compare Mega Neko, Giant Spider, Giant Crab and Big Creepy-Crawlies. For other examples of giant reptiles, see Colossal Croc and Turtle Island.

- Anaconda:
- While the snake from Anaconda (1997) is a downplayed example, being a fully-grown anaconda native to the Amazon big enough to pose a threat to humans, the snakes present in Anacondas: The Hunt for the Blood Orchid and onward are more straightforward examples; the second movie has snakes that have been made massive from exposure to the blood orchid and through scientific experimentation with black orchids in the third and fourth movie.
- Anaconda (2025): Subverted when the film crew use a real life, normal-sized, and actually quite docile anaconda as the threat in their monster movie, but Double Subverted when they stumble into the hunting territory of a mythological, giant anaconda which appears to be even larger than the one in the original film, closer to the ones in Blood Orchid that grew so large because of an Applied Phlebotinum.

This film actually spawns a trilogy, with the third movie having a serpent large enough to battle a dozen T. Rexpy-dinosaurs all at once.
- The Snake Prince ends with the titular Prince revealing his true form in the final scene after being exposed to Sulphur smoke — as a giant serpentine beast.

- The Sorcerer and the White Snake, an adaptation of the Chinese fable The Legend of the White Snake, probably contains the largest depiction of the titular character.

This snake is the greatest danger in the pits and was the method Tostha intended Conan to die from, which he only avoided by managing to stay motionless when Satha was near, even while a drop of venom burns him. He also inadvertently helps Conan escape by killing the former chief-turned-slave who came to kill him and letting Conan take his keys. As one of the "scaled people" he can see more than mortal eyes, so when seeing Pelias's "naked soul" he turns and flees.

- Aboriginal Australian Myths: The Rainbow Serpent is an umbrella term for several snake divinities in these myths, most of which traditionally having little to do with each other. Some like Wungurr (from the "Wandjina-Wungurr" cultural complex in Kimberley) are essentially abstract Life Energy, while the Gamilaraay Garriya is simply a water monster. Examples of more concrete deities include Wonambi from the Wiradjuri and Wagyl from the Noongar, which are closer to what people typically envision the rainbow serpent to be (a Fertility God associated with water with intersex features responsible for shaping the landscape).

Because of the many possibilities of his location, he eventually earned the epithet World-Encircler, and as a perpetual resident of the underworld (since Ra trapped him there), his roars would shake the underworld, while his movements caused earthquakes. There are also several other gigantic divine snakes that are actually heroic and assist Ra and the other gods at battling Apep, such as the guardian serpent Mehen, who protects Ra, his allies, and the solar barque from Apophis and other dangers that lurk in the Duat.
- Hindu Mythology has several, but perhaps the most famous is Ananta Shesha, a giant, multi-headed cobra who serves as the couch of Vishnu the Preserver. He is said to have anywhere from five to five million heads, each one constantly sings the glories of Vishnu from each of his mouths, while the entirity of all creation is carried on his hoods.

- The Mapuche people of Chile have the legend of Trentren Vilu and Caicai Vilu (also known as Trengtreng or Tenten and Kaikai); they are gigantic serpent brothers who lived in the land and sea, respectively. One day, Caicai felt unappreciated by the humans and attacked them by sending a flood. Trentren helped the humans escape the rising water and then had a long battle with his brother, which shaped the land into Chile's current geography. Trentren won since Caicai didn't flood the entire world, although the sea level didn't lower. Now, years after their battle, Trentren manifests itself with earthquakes and volcanic eruptions, while Caicai causes tsunamis and floods when it rolls around in its sleep.

- The Day After Ragnarok: After the Nazis are able to delay World War II just a bit longer, they use that to summon Jörmundgandr, whose head is stated to be 350 miles wide.

The consequences of its death, called Serpentfall, triggered a massive global cataclysm, with rain and tsunamis scattering its mutagenic blood and venom worldwide. Its body is now essentially a new mountain range reaching from Egypt, across Western Europe and to the British Isles and then looping around to cross North Africa.
- In Nomine: At its height, Jormungandr was so huge that it could coil around the entirety of the world. Currently, following centuries of recovery after being decapitated, it's only regrown to the point where its head is sixty yards long and it stands two stories tall when rearing up.

- Frogmonster: Two of the bosses:
- The Long Beast boss is a giant snake-monster, that you fight after jumping down a chasm. You reach a circular arena surrounded by walls, but then the Long Beast raises it's massive head, hisses at you, and you realize the arena's walls are actually parts of the boss' body.

- Jurassic World Alive: The Apex and Unique Raid bosses Hydra Boa and Troodoboa are large enough that even when coiled they stretch the entire width of the Jurassic World main thoroughfare and still look the giant sauropods like Brachiosaurus in the eye. Their playable versions while significantly smaller, are still the largest non-dinosaur creatures in the game, alongside the other snake hybrids Spinoconstrictor and Dilophoboa. Fittingly, this is due to them all sharing the same rig and animations made for the massive Titanoboa and Titanoboa Gen 2, the latter of which is needed to hybridize and level up Troodoboa, and the former needed to hybridize and level up both Dilophoboa and Spinoconstrictor.
- Jurassic World: The Game:
- Titanoboa, Dilophoboa, and Gigantophis easily rank among the game's largest Cenozoic creatures, as they are big enough to occupy at a significant portion of their entire enclosures, which are big enough to house the elephant-sized sloths Megatherium and Eremotherium, among other mammalian giants. Their feeding animations also come off as a little overkill, since the dodos used to feed all Cenozoic predators are small enough that the snakes can swallow them whole without effort or risk of injury.
- The snake boss Ouroboros could easily be considered a contender for the largest creature in the game, as it's arena is little more than a small canyon and it's still big enough to take up most of the space inside it.
- Krut: The Mythic Wings, a game based on Thai myths, have two different naga (giant serpentine monsters with draconic features from Thai folklore) as bosses. The first boss is a benevolent Green Naga who fights you in a Secret Test of Character, and later you battle the Black Naga in the seas who overlaps with being a Sea Serpent.
- The Last Faith have an area in the castle filled with gigantic serpents, each of them large enough to swallow your protagonist with a single gulp. You need to fight their heads, one at a time, to proceed.

- The Paleogene period hosted a wide variety of giant snakes.
- The largest known snake species to ever exist was Vasuki indicus from India, then an island continent. It's estimated that it grew up to 14.8 meters (48 feet) long. As it probably inhabited coastal swamps when it was alive, it may have been amphibious and would have mostly eaten fish, other reptiles, and mammals, among which were the early, semi-terrestrial ancestors of whales.
- The previous record holder (lengthwise) was Titanoboa cerrejonensis, a member of the boa constrictor family that existed in the Paleocene Epoch (around 60 million years ago) that grew to be at least 13 meters (42 feet 3 inches) in length and weighed more than a ton (making it heavier then Vasuki). Given its massive bulk, it spent its life in the Amazonian swamps of modern-day Colombia. If Titanoboa still lived today, it could kill and eat a full-grown horse. While it was initially thought to be an apex predator that fed on large mammals and crocodiles, more recent discoveries of fossils of its head and jaws have led scientists to believe that it was instead a specialist fish-hunter.
- Third to Titanoboa and Vasuki, Gigantophis was a large prehistoric snake that lived in North Africa 40 million years ago, estimated to be over 10 meters long; though a later study adjusted this length estimate to 6.9 meters, much closer in size to the largest extant snakes. Like Titanoboa and Vasuki, it probably lived in hot, swampy environments (North Africa wasn't a desert yet), where it fed on large fish and mid-sized mammals, such as the pig-sized ancestors of elephants.
- Palaeophiids
were a group of large sea snakes, members of whom could grow up to 5 to 12 metres.
- Measuring living snakes isn't an easy task, but as far as anyone knows, the largest extant snakes are the Reticulated Python (Malayopython reticulatus), which can reach 25 feet, and the Green Anaconda (Eunectes murinus), whose maximum length is unknown but several skins exist which came from individuals at least 24 feet long.note Given the anaconda's proportions, a 24-footer would weigh in the neighborhood of 400 pounds. The longest extant venomous snake is the King Cobra (Ophiophagus hannah), with a record length of 18 feet and an average of over 10. Besides its extreme length and potent venom, the King Cobra is also a highly alert snake with the capacity to raise almost half of its body length off the ground, meaning it's a Great Serpent that can look the average human in the eye. Naturally, it was an inspiration for myths and religious practices in the places where it's native. The Basilisk is probably based on cobra sightings.
