The Kesprytt Republic was a planetary state of the planet Kesprytt III formed at some point in the 24th century.
While the planetary government was tasked with relations with other spacefaring civilizations, because of the long conflict between the Kesprytt species' nations of Kes and Prytt, its form of government was a "split republic" that maintained the divisions between the two peoples.
One of the prime ministers of the Kesprytt Republic during the 24th century was Sarin. (ST video game: Infinite)
- In ST video game: Infinite, The Kesprytt Republic exists already by 2346, with Sarin as its prime minister. While it contradicts TNG episode: "Attached", where the two nations are entirely divided by 2370, it was likely done for gameplay reasons, as the game's engine does not allow for two separate governments to exist on one planet.
