Steven Universe has Delmarva (where most of the show is set), Keystone, Empire State (and Empire City) and Jersey (no New)…
Aside from Delmarva they all seem to be simply different names for real-world states (taken from the nicknames of Pennsylvania, New York, and New Jersey), though. (Delmarva may be the entirety of Delaware, Maryland, and Virginia, or it may just be the Delmarva peninsula and some other nearby portions of those states).
This reminds me of Vanished Kingdoms: The History of Half-Forgotten Europe A darn good read:)
New Wapping Old Stairs? 
You’ll have to amend that to New North Wales as Australia beat you to it.
Do you want the reader to be gulled into believing the fake country is real? With a miscellany of small countries in the Caribbean, Africa, Central Asia or Latin America fake names for those regions are easy. The Islamic Republic of Sawarak, Malaccan Federation or Emirate of Hejaz might do for a small Islamic state in SE Asia or the Middle East. A new small country in Europe requires greater care but is still doable.
But for an imitation Canada or Israel I assume you expect the reader to know it’s a fake country, right? Try: Nova Mercia, Hudsonland, (Great) Caledonia, or the Commonwealth of New Britain.
Imitation Israel is tougher. The State of Sinai and Zion? The Confederation of Judaea? How do you say ‘New Zion’ in Hebrew?
New Newcastle
As a matter of fact, there’s a wiki entry for those. My favorite is probably Callisota, home of Duckburg. (And there are numerous indictations, in various media, that Callisota is carved out of a section of Northern California)
(The “s” is backwards.)
For awhile I was wondering how Marvel could get away with making fun of Latvia until I realized the comic book country’s actual name is Latveria.:smack:
And it’s right next to Dilbert’s Elbonia.
Living in Maryland I tried to figure out which town Beach City was a parody of. Rehoboth was as close as I could come and in RL seems much too large. Of course trying to figure out the location of a cartoon city is as pointless as trying to figure out which state the Simpsons live in.
Can’t remember which book, but P.J. O’Rourke once made a passing reference to the middle eastern country of Trashkanistan.
According to Steven Sugar, it’s not a reference to any one city, just to the beaches in the area the Sugar family visited when he and Rebecca were kids - including specific references to Rebohoth, Bethany, and Dewey Beaches.
H.L. Mencken used to disparage the Maryland Eastern Shore as “Transchoptankiana”.
Reported.
It doesn’t follow the “San” format, but El Salvador is directly called God (“Our Saviour”)
Writers who do the “San” thing and manage to actually get the grammar and spelling right are extremely rare, sadly, even when a quick google could tell you that it’s Santa Marta and not “San del Martha”.
Similarly, there’s a book in the amateur library I organize called Crown of Dalemark. I don’t know how many times I’ve reshelved that book before I realized that it’s a fictional country, not Denmark.
Delmarva should just be changed to “Downyoshun.”
That one has confused me because I’m unfamiliar with the source. And now Nagorno-Karabakh has changed its name to Artsakh, which sounds a lot like it.
Thank you! I was going to look it up, because I remembered it being something like Gibeah or Gilead, but I wasn’t sure what.
Two of my favorite Ruritania names are Vlatava and Modora, from DC Comics. Also Ruritania, of course. DC has a lot of little made-up countries, to the point they have had a couple of places nuked or otherwise completely destroyed for the sake of a story.
Bill Willingham’s Coventry was a horror comic book in the USA state of Coventry, which might be somewhere near Oregon, as I recall.
Israel is too “unique” to allow “another Jewish country like it” to feel non-fantastic in the present day. But you could have a made-up Jewish community parallel to Litvaks, Yemeni Jews, or the like.
Canada has a similar problem, because it’s so big and part of region notoriously divided between two powers. It’s like coming up with another Russia or China or USA. You could come up with a province, I suppose.
For the Nordic region, you could just use a real local name, I suppose. Åland, Öland, Grenland (not the same place as Greenland), North Schleswig, Limberwisk, Estonia, etc. It works as an in-joke for those who know the real place.
