Aýna[1] (Spanish pronunciation: [aˈina]) is a small village and municipality in the southern region of the province of Albacete, in the Spanish autonomous community of Castile-La Mancha.

It is a popular summer vacation destination due to its pleasant scenery and climate.

Aýna is referred to as "Manchegan Switzerland" due to its location between two mountain ranges.

[1] The spelling of the town preserves an archaic[2] use of the letter ⟨y⟩, which was common in Old Castilian.

[3][1][4] The spelling is notable for having one of the only Spanish language use of the character ⟨ý⟩.
