Ribagorçan (autonym: ribagorsano or ribagorzano)[a] is a number of Romance dialects spoken in the modern territories of the medieval County of Ribagorza, in northern Spain.
Being predominantly a spoken language, written documents are scarce, but they do exist—most notably, the Pastoradas of Benabarre compiled by Ricardo del Arco as well the writings of Tonón de Baldomera and poetry of Cleto Torrodellas; and more recently works by Ana Tena Puy, Carmen Castán and Bienvenido Mascaray Sin.
With the recognition of Aragonese as a language in 2003, intra-regional identities, among them Ribagorçan, have gained strength, and there is renewed interest in preserving, teaching and developing the local dialects commonly referred to as fabla.
In Aragon, the dialect in Ribagorza can be clustered into two main groups: Upper and Lower Ribagorçan defined by an isogloss line running east–west from the Turbón mountain.
A dialectal variant exemplified by the Ribagorçan speakers of Pont de Suert, is Catalan dominant transitional to Aragonese with some traits of Aranese Gascon.
