The term Basque Derbies refers to the various football local derbies between the teams in the Basque Country (autonomous community), Spain. It specifically refers to individual matches between the teams, but can also be used to describe the general ongoing rivalry between the clubs and fans.
As of the 2017–18 season, there are four clubs in La Liga that play in the Basque Country area. The major rivalry is between Athletic Bilbao and Real Sociedad, known as the Basque derby.
The relationship between the two smaller clubs, Deportivo Alavés and SD Eibar, became more strained in 2017 when Eibar's farm team (CD Vitoria, based in Alavés' home city of Vitoria-Gasteiz, competing directly with the Alavés reserve team and previously an affiliate of that club) gained promotion and upgraded to municipally-owned facilities in the town. A short time beforehand, Alavés had acquired the services of Eibar's youth academy director.
Another major club in that part of Spain, CA Osasuna based in Pamplona, is sometimes considered to be a Basque organisation due to the cultural ties with their homeland of Navarre (part of the greater Basque Country), and at times their relationship with the neighbouring teams has been hostile. However Osasuna have their own inter-regional rivalry with Real Zaragoza of Aragón.
