José Miguel Beñaran Ordeñana (1949 – 21 December 1978) was a Basque paramilitarist and a key figure in the political evolution of the Basque separatist paramilitary Euskadi ta Askatasuna (ETA).
Often known by his nom de guerre Argala (Slim), he took part in the so called Operation Ogre, which consisted in the assassination of Luis Carrero Blanco, Spain's Prime Minister, in 1973.
Five years later, he was in turn assassinated by a car bomb in Anglet, French Basque Country by a group directed by far right members inside the Spanish Navy (including an official of the SECED secret service and another of the Naval military intelligence agency, Servicio de Inteligencia Naval and the other belonging to the Alto Estado Mayor).
This group reportedly received assistance from people such as former OAS member Jean Pierre Cherid, former Triple A Argentine member José María Boccardo and Italian neofascist Mario Ricci, member of Avanguardia Nazionale.
