The Torneo Súper 8 de Básquet (English: Super 8 Basketball Tournament) was a professional basketball national domestic cup competition that took place each year between teams from Argentina's top-tier level basketball league, the Liga Nacional de Básquet (LNB).
The Torneo Súper 8 took place during the middle of the season, usually in the month of December, before the Argentine League's year-end recess.
It was an 8 team single-elimination knockout tournament, and was held in one arena.
It was held under a format similar to that of the Spanish King's Cup.
The winner of the tournament received a place in the FIBA South American League.
