* In ''[[https://www.fanfiction.net/s/8106168/6/Weres-Harry Weres Harry]]'' Tom Riddle's shade was extremely upset that Ginny had given his diary to Luna.
-->"...The Weasley brat is the seventh child and first daughter born in seven generations. Sacrificing her soul while absorbing her magic would have been enough to give me life of my own..."
* In ''FanFic/SonOfTheDesert'' Trisha is the seventh daughter of a seventh daughter, a batsheva, which means she has a sacred place in Ishvalan society. In-universe, few people in Ishvalan society are allowed to refer to someone by their first name, and there are strict cultural rules dictating respect and deference in conversation. In contrast, everyone is allowed to call Trisha by name (and vice versa), she can speak her mind at any time to anyone she wants (including talking back, even as a very young child), and marrying her will allow someone to start a new family name. She marries [[spoiler: the immortal Hohenheim.]]
* In ''Fanfic/TheAwakeningOfAMagus'', it turns out [[spoiler:Ron is very powerful magically]] due to being one; [[spoiler:Percy had a twin brother who died a day after being born.]]

* Taken UpToEleven in Creator/OrsonScottCard's ''Literature/TheTalesOfAlvinMaker''. Alvin is not only a seventh son, he is the seventh son of a seventh son, his parents' thirteenth child, and to top it all off was born with a caul, and is a powerful "maker" -- a rare and powerful form of magic. The first novel in the series is even named ''Seventh Son''.

* In ''WesternAnimation/BarbieInTheTwelveDancingPrincesses'', Franchise/{{Barbie}} plays the protagonist Genevieve, the seventh of the twelve sisters.

* It doesn't come up as an important plot point in ''Literature/HarryPotter'', but WordOfGod notes that Ginny being the seventh child in her family (albeit the [[OutnumberedSibling first daughter]]) was supposed to symbolize her as someone special. She is also the first girl born into the Weasley family in several generations.

A subtrope of RuleOfSeven, related to LuckySeven.

* In ''WesternAnimation/BarbieInTheTwelveDancingPrincesses'', Barbie plays the protagonist Genevieve, the seventh of the twelve sisters.

* According to the remake, Aarbron was the seventh offspring of a seventh child. This is the reason he was chosen to become the beast messenger.

* In ''Webcomic/ByTheBook'' Septimus Volk first mentions that he's a seventh son [[http://bythebook.smackjeeves.com/comics/1642640/pg6/ when explaining why]] he's somewhat short on funds despite being of noble birth. The magical part isn't really mentioned until he takes [[RPGMechanicsVerse a level of wizard]] and casts an [[http://bythebook.smackjeeves.com/comics/1865730/pg39/ unusually powerful]] MagicMissile.

* The brazillian webcomic "Sétimos Filhos" ("seventh children") is a slice-of-life story about a pair of twins who were both born as the seventh child, and thus, were both cursed, with the male sibling becoming a werewolf and the female one becoming a witch.

* In Myth/BrazilianFolklore, the seventh child of the same gender in a row becomes a werewolf. Other legends say that the eighth female child becomes either a Cumacanga (in other words: A woman whose head detaches from her body at night and floats around, on fire, scaring people)or a witch.

* In the ''Series/SesameStreet'' song "The Alligator King," the seventh son has a thoughtfulness that proves to be pretty magical ... by just offering a little help, he proves himself worthy and wins the crown. (Pity it cost [[AllThat Glitters all of seven cents]].)

** In ''Literature/{{Sourcery}}'', we learn that the eighth son of an eighth son of an eighth son becomes a super-powerful "sourcerer", a wizard that is actually a source of magic, and almost [[AGodAmI too powerful]] for the world to bear. (This is one of the reasons wizards are discouraged from having sex.)

Traditionally, this trope was AlwaysMale, possibly because "seventh daughter of a seventh daughter" doesn't quite roll off the tongue. (Though it's more likely for less [[DoubleStandard charitable reasons]].) Modern works, however, have an increasing tendency to feature the distaff version -- especially in FeministFantasy, where the author may explicitly add a "take that!" comment about the traditional version. Speaking of gender politics, this trope may even overlap with SupernaturallyValidatedTransPerson if these powers confirm that the seventh son ''is'' a son, or that the seventh daughter ''is'' a daughter.

* In ''WesternAnimation/BarbieInTheTwelveDancingPrincessess'', Barbie plays the protagonist Genevieve, the seventh of the twelve sisters.

The number seven is often [[RuleOfSeven considered magical]], and in [[OralTradition folklore]], the seventh son of a seventh son is often considered to have inherent magical powers like [[{{Seer}} second sight]]. In fiction, and sometimes song, this is often shortened to just the seventh son, though seventh sons were common enough (up until the 20th Century) that this makes little sense.

A common version of the legend says that the seventh son of a seventh son will be born with a caul (actually a loose flap of amniotic sac) over his face, to [[BlindSeer signify]] the {{Seer}}-like powers.

* ''Film/The Magic Door'': Raglin is the seventh son of a seventh son, which is rare for a troll.

** In ''Discworld/EqualRites'', Eskarina ''would'' have been an eighth son of an eighth son if she hadn't been born a girl, which causes quite a lot of trouble when a wizard mistakenly bequeaths his powerful wizard's staff to her under the assumption that she would be an eighth son. [[GenderRestrictedAbility Women are supposed to be witches]], not wizards, so most of the story is spent trying to figure out where exactly she fits in the world.

* In ''FanFic/SonOfTheDesert'' Trisha is the seventh daughter of a seventh daughter, a batsheva which means she has a sacred place in Ishvalan society. Everyone is allowed to call her by name, marrying her will allow someone to start a new family name and she's free to speak her mind around anyone. She marries [[spoiler: the immortal Hohenheim.]]
