Due to the complex political makeup of the Basque Country, the picture of existing political parties, their history and political positions is equally complex.

The region is split between two states, Spain and France. On the French side, parties that are of specifically Basque coloration operate mainly at the local and departmental level, in the case of the Northern Basque Country the Département Pyrénées-Atlantiques.

On the Spanish side, the region with Basque ties is split between the Foral Community of Navarre, the Autonomous Community of the Basque Country (BAC) and the exclave of Castile and León, Treviño.

Some political parties operate only in a single region, others operate in more than one region, occasionally under a different name. They cover the entire spectrum, from ultra-nationalist parties through moderate nationalist parties, socialists, conservatives, green parties and other groupings.
