Este artigo é sobre the political entity. Para the geographical region, veja Alcaire.
Alcaire was a Third Era fiefdom on the south-central coast of High Rock, on the north shore of Iliac Bay. Shortly before the Warp in the West, it was ruled from the city of Alcaire, and bordered Koegria to the southwest, and the Wrothgarian Mountains to the north.  Following the Warp, it became part of the kingdom of Wayrest. The regional deity was Kynareth.
The book The Arcturian Heresy claims Hjalti Early-Beard was born within its borders, and that Hjalti would go on to become Tiber Septim. For this reason, the province celebrates Tibedetha (Tibers Day) on the 24th of Mid Year.
- The region shares its name and approximate geographical location with the Second Era Stormhaven duchy of Alcaire.
- In the Skyrim quest The Ghost of Old Hroldan, the eponymous ghost holds a dialogue with "Hjalti", and makes reference to the time they spent together as students of "the sword masters of Alcaire".
