Right after [[RuleOfThree three]], seven is the most commonly used "ominous" number in fiction. This can be traced back to the ancient times; just think of the Seven Wonders, the Seven Days of Creation, or the Seven Hills of Rome. It is also common in many fairy tales.

In the natural world, one of the origins of this significance come from the seven celestial bodies that could be seen with the naked eye, (Sun, Moon, and the planets up to Saturn), that were worshiped as deities, and the days named after them were the days of the week.

Later, natural phenomena were intentionally shoehorned into this "significant" number, for example the colors of the rainbow and the number of continents can be seven, depending on how you count them.

Since Literature/TheBible, especially the Literature/BookOfRevelation, uses it repeatedly, seven became even more famous as a divine number, or as the number of perfection.

LuckySeven is a subtrope about examples where it is considered a lucky number. Also see MagicalSeventhSon, SevenDeadlySins.

** Grant Morrison also did a story arc titled "Synchronicity," where various occurrences resulting from a probability-altering machine including seven separate villains attacking Washington [=DC=] simultaneously to Martian Manhunter calling in the Atom because he was the seventh "new member" since the League's inception.
* WarrenEllis often used this in his WildStorm work: the faux JLA in ''StormWatch'', the pulp era heroes in the first issue of ''{{Planetary}}'' (and the other faux JLA that they fight), and the members of ''TheAuthority'' (whose leader {{Lampshade}}s the trope).

** Seven books for seven years at Hogwarts.

* Practically every number you encounter in the ''Literature/SeptimusHeap'' series is either somehow related to the number seven (often the result of adding the numbers together), or an homage to something or other. There's even a list at the end of the first book.
* Subverted in ''Literature/{{Discworld}}'', where the most magical number is 8. Magic being a very [[SpeakOfTheDevil dangerous thing to play with]], there are a lot of superstitions around the number (some people insist on calling it "7a").
* Gilbert L. Morris' books "The Seven Sleepers" series is about seven teenagers who have adventures in a post-nuclear attacked world.

* ''ASongOfIceAndFire'': The Faith of the Seven is all about this -- seven gods/aspects of god, heptagon-shaped temples called septs ("sept" meaning seven in French), seven hells -- and the rainbow is seen as a holy symbol. Other examples include the "Seven Kingdoms" (an anachronistic title referring to the state of the realm before it was unified under a single king), the seven members of the Kingsguard, the seven Iron Islands, and there are surely many more to list. GeorgeRRMartin is currently planning on making the series seven books long; [[TrilogyCreep whether he'll actually be able to do that]] [[FourLinesAllWaiting is another matter.]]
* In Creator/EdgarRiceBurroughs's ''Literature/TheMonsterMen'', von Horn has not set foot on a place under American jurisdiction in seven years.

When her half-brother is born, he is the seventh son of a seventh son, which has great mystical meaning. Also, as the name of the trilogy mentions, they live at Sevenwaters, which has a lake in the centre with seven streams feeding into it.

** Due to escalation of the use of the SixthRanger, ''Series/PowerRangersSPD'' and ''Series/PowerRangersRPM'' eventually got seven full-time members each. (A bit of a subversion with ''SPD'', though, as the numbers on their suits were 1, 2, 3, 4, 5, VI for 6, and... 100.)
** ''RPM'' also finished its run, and with it Disney-produced new episodes, with the franchise's 700th episode. Incidentally, it was Season 17.

[[folder:Religion and Mythology]]
* Several religions regard 777 (RuleOfThree and RuleOfSeven united) as special:
** According to the American publication, the Orthodox Study Bible, 777 represents the threefold perfection of the Trinity. Satan the arrogant and imperfect, is represented with 666.

* In UsefulNotes/Islam odd numbers in general, and especially odd primes, are considered auspicious, as they represent the unity and indivisibility of God; therefore, it shouldn't be any surprise that seven shows up at several points in Islam, although not as much as five. The most prominent is probably the ''Iman al-Mufassil'', or Detailed Statement of Faith, in Sunni Islam, which states: "I believe in God [1] and His Angels [2], His Books [3] and His Messengers [4], in the Day of Judgment [5], that all things good or ill are the will/fate of God [6], and in resurrection after death [7].

* All over the place with ''PunchOut'' Wii's version of Aran Ryan. He always gets up from a knockdown on the seventh count, you can hit him seven times when he's stunned, and sevens pop up in his challenges in Exhibition Mode. He's Irish, so it's a "lucky seven"/"luck of the Irish" gag.
* ''FinalFantasy'':
** ''VideoGame/FinalFantasyVII'' (figures) has something interesting happen if a character's HP hits 7777. The Lucky Seven concept continues in the prequel ''CrisisCore'', where getting three Sevens on the Digital Mind Wave (the battle system's slot-machine gimmick) will level up your character.

In ''VideoGame/NoMoreHeroes2DesperateStruggle'', both training courses in Ryan's gym have seven levels each.
* In the backstory of the ''Franchise/DragonAge'' games, Chantry lore claims that the Blight appeared on Thedas when seven ancient Tevinter Magisters traveled to the Golden City of the Maker in an attempt to steal his power. Their invasion of the City corrupted it into the Black City, and they returned to Thedas as the first Darkspawn. [[spoiler:The Chantry's lore is all but confirmed in the VideoGame/DragonAgeII DLC "Legacy" with the appearance of Corypheus, one of the original Magisters, who acts as the FinalBoss.]] There are also seven old gods, which means there should be seven blights.

* Seven continents on Earth
* Seven seas
* Seven days in a week
** Which is, in turn, caused by the presence of seven celestial objects regularly visible from Earth — the sun, moon and five planets.
* Seven colours of the rainbow. This is actually a [[AssPull contrivance]] of Sir IsaacNewton, a well-known scientist and not-well-known mystic. [[NewerThanTheyThink Observing the spectrum of sunlight produced by his prism]], he convinced himself that the area between blue and purple was a separate colour, indigo, because seven colours would fit his numerology better. The joke of this is, he missed a ''real'' seventh colour: cyan, between green and blue. In Russian language, [[http://blog.properrussian.com/2011/05/what-colors-are-there-in-your-rainbow.html cyan IS addressed as the true seventh color]].
* As a homage to this trope, the highest jackpots on a slot machine is often assigned to three 7s.
* 21 (7×3) in blackjack.
* Seven is the most likely roll of a pair of standard six-sided dice. In craps, you can win by rolling a seven (or eleven) first, and lose by getting seven on any subsequent roll. The fact that seven is the most likely sum for the outcome of rolling two dice (with a probability of 1/6) is likely the origin of the whole "seven is a lucky number" superstition.
* In chemistry, the pH scale is neutral at 7. And it's not arbitrary at all, since H+ molarity in water is approximately 10^(-7), and pH is a logarithmic scale (though the mole's value, from which molarity comes, is indeed a fixed one).
* The number of daughters of Atlas in the Pleiades (also called the "Seven Sisters").
* And by analogy, "The Seven Sisters" is used to refer to:
** The seven historic women's colleges of the United States (Barnard, Bryn Mawr, Mount Holyoke, Radcliffe, Smith, Vassar, and Wellesley).
** The seven largest oil companies in the world from 1940 to 1973. More specifically, they were part of the Consortium for Iran oil cartel. Before they were sidelined by OPEC, the seven were responsible for a rather large amount of unpleasantness in the Middle East. They are (current names): BP, Gulf Oil, Chevron, Royal Dutch Shell, Esso, Exxon-Mobil, and So Cal.
** The original seven Hollywood film companies.
** The seven main denominations of the American Protestant church: Episcopalian, Lutheran, Methodist, Presbyterian, Congregationalist, Baptist, and Reformed.
* Almost all mammals have seven cervical vertebrae.
* A ladybug has seven spots.
* Seven is the atomic number of nitrogen, which makes up the majority of Earth's atmosphere.
* Ask people to randomly choose a digit from 0 to 9 and they're more likely to pick 7 than any other.
* In physics and metrology, there are seven SI base units: Meter (length), kilogram (mass), second (time), kelvin (temperature), mole (amount of substance), ampere (electric current), and candela (luminous intensity).
* Television channels with the number seven love this.
* Microsoft Windows 7, the first to use the numbering scheme in its marketing since way back with Windows 3.1.
* The reason Creator/IanFleming gave Literature/JamesBond the number 007 is because of RealLife Elizabethan spy John Dee, who would sign his letter to Queen Elizabeth I as "007" - the 00 indicating the letter was for her eyes only, and "7" being the [[LuckySeven luckiest number]].
