A comarca (Spanish: [koˈmarka], Portuguese: [kuˈmaɾkɐ] or [koˈmaʁkɐ], Galician: [koˈmaɾka] pl. comarcas; Catalan: [kuˈmarkə] 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]).
The term comarca is used in several regions of the Iberian Peninsula.
In other places, such as Extremadura, the comarca may be simply a loosely-defined region.
Because of the comarca's long-standing use, it is sometimes used as the basis for the promotion of tourism, with emphasis on local cultural tradition and history.
In Panama, the comarca indígena is an administrative region for an area with a substantial Indian population. Three comarcas (Comarca Emberá-Wounaan, Kuna Yala, Ngöbe-Buglé) exist as equivalent to a province, with two smaller comarcas (Kuna de Madugandí and Kuna de Wargandí) subordinate to a province and considered equivalent to a corregimiento (municipality).
