The Catalan language is a Romance language spoken primarily in eastern and northeastern Spain, specifically within Catalonia, Valencia, and the Balearic Islands.12

Beyond Spain, the language is spoken in the following regions:

Andorra: Where it serves as the official language.1
France: Specifically in the Roussillon region.1
Italy: In the city of Alghero on the island of Sardinia.1

While there are regional variations in dialect, such as the western group (including Valencian) and the eastern group (including Balearic and Roussillonnais), these are generally considered mutually intelligible forms of the same language.12
