JEL (Jaungoikoa eta Lagi-zaŕa, "God and the old law" in Biscayne Basque, Lege-zaharra in Standard Basque) is the motto of the EAJ/PNV, the Basque Nationalist Party of Spain. The "old laws" referred to are the fueros, privileges granted to the Basque provinces by Spanish kings which were revoked after the Carlist Wars.

JEL is the origin of jelkide ("JEL-companion", EAJ-PNV member) and jeltzale ("JEL-follower", as in the gloss of EAJ, Eusko Alderdi Jeltzalea).
