I would normally translate this as the Catalan Countries - in some cases I'd also include the Catalan original name - Països Catalans.

Catalan is the language of Catalonia, as well of as of other regions. The native spelling of this romance language is Català. In all, 7 million speakers make this language the most vigorous minoritized language of Europe. The term Països Catalans or Catalan Countries is used by some (by us, for instance, in GeoNative) to name the regions where catalan language is spoken. These are the following:

* Andorra. Independent little state in the Pyrenees, where catalan is official
* Catalonia. Four provinces under Spain
* Northern Catalonia. The region under France.
* Catalan language area in Aragon, in Spain.
* Valencia. Three provinces under Spain.
* Balearic Islands, in Spain.
* The city of L'Alguer, in Sardinia (Italy).

The term Catalan Countries (Catalan: Països Catalans) includes all territories where the Catalan language is spoken. This concept first appeared at the end of the 19th century and later was popularized by the Valencian writer Joan Fuster, in his book Nosaltres els valencians ("We, the Valencians") (1962) with a very strong sense of Catalan identity. Nowadays, the term is politically charged, and also tends to be closely associated with Catalan nationalism and Catalan independentism.

The "Catalan Countries" are sometimes referred to by Catalan nationalists el pi de les tres branques (the three-branched pine, in Catalan), for its territory can be roughly divided in three parts:

* The former Principality of Catalonia, comprising:
o the current Spanish Autonomous Community of Catalonia (Catalan: Catalunya or Catalunya del Sud)
o Northern Catalonia (or Pays Catalan), in France (Catalan: Catalunya (del) Nord)
* The former kingdom of Majorca : the Balearic Islands (Catalan: Illes Balears i Pitiüsses)
* The former kingdom of Valencia: Land of Valencia (Catalan: País Valencià)

All of these were part of the Catalan-Aragonese Confederacy; all were outside of Aragon proper.

In addition, the term also often embraces

* La Franja in Aragon (a Catalan-speaking region that is part of Aragon proper)
* Andorra (geographically adjacent, linked by language, but never under the same political dominion in the period where a distinct Catalan language has existed.)

This territory does not coincide exactly with the places where Catalan is the native language. For example, in the north-western region of Catalonia known as Val d'Aran, a dialect of Occitan, Aranese, is spoken and considered the native language, although Spanish and Catalan are also spoken. In western and south-western areas of Valencia, only Spanish is spoken. There are also some Catalan-speaking places outside the "Catalan Countries", such as El Carxe in Murcia and the city of Alghero (L'Alguer) on the island of Sardinia.
