A comarca (Spanish: [koˈmaɾka], Portuguese: [kuˈmaɾkɐ] or [koˈmaʁkɐ], Galician: [koˈmaɾka] pl. comarcas; Catalan: [kuˈmaɾkə] or [koˈmaɾka], pl. comarques) is a traditional region or local administrative division found in parts of Spain, Portugal, Panama, Nicaragua, and Brazil. The term is derived from the term marca, meaning a "march, mark", plus the prefix co- meaning "together, jointly".
The comarca is known in Aragonese as redolada (IPA: [reðoˈlaða]) and in Basque as eskualde (IPA: [es̺kualde]). In addition, in Galician comarcas are also called bisbarras (IPA: [bizˈβaras]).
