Exactly What It Says on the Tin: When a character is referred to pretty much exclusively by where they come from. Or at least, where everyone assumes they're from. The entire name doesn't have to be shared with the place, the hometown can just be part of the nickname, i.e., Troperville Ted or Ted from/of Troperville. This is Truth in Television, if you look in historical documents, you will find that many people were distinguished by where they came from (other common identifiers included trade or profession and distinguishing features). When surnames became common, towns of origin were often assigned as family names. If the person isn't actually from the place they are named for, it can become an Ironic Nickname. This is also one popular means for pen names.
- Kasuga Ayumu in Azumanga Daioh is only known as Osaka.
- Trope was enforced in-universe by one of her new friends, whose idea the nickname originally was. Also lampshaded/discussed as said friend declared on the spot that shows have characters from Osaka only known as Osaka (and that such is funny). Never mind that Ayumu points out she spent only a year or so of her life in Osaka; the friend is a Giver of Lame Names.
- Elie in Rave Master, who asumes the tattoo on her arm is her name after getting Laser-Guided Amnesia. It's actually both her home town and the coordinates of said town.
- In Bleach there's Kenpachi Zaraki and Yachiru Kusajishi, both of whom didn't have last names, and so they took the districts they originated from (Zaraki and Kusajishi, respectively). In Kenpachi's case, its even more so, since Kenpachi is a title given to the strongest Shinigami. So he's really 'The Kenpachi from Zaraki'.
- Some writers of Superman comics have picked up Lois calling Clark "Smallville" from Superman: The Animated Series and Smallville.
- Dennis Finnegan, a gangster who was framed for murder by corrupt cops in the Robin Series, is called Dublin because he's from Dublin Ireland.
- Wonder Woman Vol 1: It is unclear if Virginia True's first name is a nickname or her legal name given how the Holliday Girls treat nicknames, but either way the name originates from her home state.

- Enforced in-story in the Hetalia: Axis Powers High School A.U. fanfic Outcast — the St. Hetalia Academy for Boys recruits one student from every nation, and students are referred to by their country of origin for the duration of their studies. Calling another boy by his real name can be seen as an insult (if done in a public setting) or as an intimate act (if done in private).
"I'm Tino Väinämöinen," I said, hoping to get the full story right away."That's just your real name," the boy said casually. "We don't use them here at St. Hetalia. We call each other by the names of our countries, sort of like code names. Your name here is Finland."

Another boxer mentioned in the same dialog is Tex Colorado a.k.a. the Arizona Assassin who hailed from North Dakota and who had a brother named South Dakota who somehow came from West Virginia.
- Poolhall Junkies - The Greek.
- Almost every character in Zombieland. At first it's just something that Tallahassee insists on to avoid emotional ties with other survivors, but through the course of the movie, almost every character ends up only being identified by where they are from (or, in the Flash Back, by their apartment numbers), with the only exceptions being The Cameo and, at the end of the movie, Wichita.
- Alabam, Grady Sutton's character from Hal Roach's "Boy Friends" short subject series from the 1930's.

- A fairly well-known example from The Bible is Jesus of Nazareth, sometimes also known as The Nazarene.
- A few other names in the New Testament and early saints fit this pattern, which is not all that surprising due to some given names being extremely popular, e. g.

Averted by Saul of Tarsus, who changed his name to Paul - just Paul.
