Fuero (Spanish: [ˈfweɾo]), Fur (Catalan: [ˈfuɾ]), Foro (Galician: [ˈfɔɾʊ]), Foru (Basque: [foɾu]) or Fueru (Asturian: ['fweru]) is a Spanish legal term and concept. The word comes from Latin forum, an open space used as a market, tribunal and meeting place. The same Latin root is the origin of the French terms for and foire, and the Portuguese terms foro and foral; all of these words have related, but somewhat different meanings.
The Spanish term fuero has a wide range of meanings, depending upon its context. It has meant a compilation of laws, especially a local or regional one; a set of laws specific to an identified class or estate (for example fuero militar, comparable to a military code of justice, or fuero eclesiástico, specific to the Roman Catholic Church). In many of these senses, its equivalent in medieval England would be the custumal.
