Island Country Name Generator
Invented island nations for maps, stories and games
Generate names for fictional island countries: 1,000 invented states such as Republic of San Corvo, Kingdom of Tavuna, Saint Brenna and the Leewards, Sultanate of Pulau Seri and Vestroy, with forms of state from federated atolls to bailiwicks.
About island country names
An island country's name usually says how the country is put together. Real ones show the patterns: a saint and a second island joined by "and" in the Caribbean, federated states spread across Pacific atolls, and kingdoms, sultanates and bailiwicks where an old title stuck. This list of 1,000 invented names follows the same logic, so the entries read as states and not as single rocks: Republic of San Corvo, Kingdom of Tavuna, Saint Brenna and the Leewards, Sultanate of Pulau Seri, Bailiwick of Hartsey.
The names fall into regional styles. There are Caribbean saint-and-island republics, Polynesian- and Micronesian-sounding kingdoms and federated atolls, Malay-flavored and Indian Ocean sultanates, Mediterranean principalities, Norse and Gaelic island realms, two-island unions, crown dependencies and overseas territories, tiny free ports, settler dominions with a "New" in front, and fantasy sea-kingdoms. About a quarter are single coined words such as Vestroy, Kavalu or Marivia, for when the map label has to be short.
The foreign-sounding names follow the sound patterns of their regions and carry no claimed meanings. They are made up, but a coined word can still match a real place somewhere, so search any name before you publish it.
How to choose island country names
- Choose the form of state before the name. A federation or union implies islands that bargained their way together, a kingdom or sultanate implies one ruling house, and a bailiwick or overseas territory implies a larger power somewhere over the horizon.
- Use the "and" pattern for a country with a junior partner. Corvane and Little Corvane or Saint Tamsin and the Petrels tells readers at once that one island feels overlooked by the other.
- Keep the sound of the country consistent with its towns and people. If the state is Lotuvea, its capital should not sound Norse, and the word for its citizens (Lotuvean) should be easy to say.
- Give the country a formal name and a short one. Maps and passports can say Commonwealth of the Sable Cays while characters just say the Cays.
- For alternate history, a settler-style name such as Dominion of New Sorrel or Nieuw-Walcheren hints at who arrived and from where without a paragraph of backstory.
Frequently asked questions
What makes a name sound like an island country and not just an island?
A form of state or a clear country shape. A cay is a place, but United Cays of Halyard Sound is a government, and Saint Corwen and Marrow Island is a union of two islands. Single coined words such as Insulania or Tevaru also read as countries because they have no island word attached.
Are these real countries?
No. The list is 1,000 made-up names for fiction, games, maps and classroom projects, and none is meant to stand for a real state or territory. Because a coined word can coincide with a real place, look a name up before you use it in something public.
Which island country names suit a fantasy setting?
Look for the sea-kingdom entries, such as Sea-Kingdom of Tidecrown, Thalassocracy of Vael Maris or Realm of the Hundred Sails, and the Norse-flavored realms like Jarldom of Haldrey. The single-word names also work in fantasy because they carry no real-world title.
Can I use these names for a thriller or an alternate-history map?
Yes. The modern-sounding entries are built for that: Free Port of Lantern Rock, Crown Dependency of Marrow Sound and Federated Atolls of Ruwalik read like states with flags and customs posts. Add a capital, a currency and one neighbor, and the country will hold up for a whole plot.
