This is a list of flags of provinces of Spain. The flags are listed per autonomous community. The list also discusses coat of arms as most flags feature them.
In addition to the provinces which have no official flag (A Coruña, Zamora and the whole Valencian Community: Alicante, Castellón, Valencia), which sometimes use erroneously the capital town flag, or with the variants sometimes used by official institutions (like Diputación Provincial, for example ) there might be some other confusion and controversies with background colour of the ones of Gipuzkoa ( instead of ) and Badajoz ( instead of ), not for the coat of arms.
