The Torneo del Interior is an annual rugby union competition in Argentina. The competition involves clubs from all provincial unions outside of Buenos Aires. Teams qualify from the Litoral, Noroeste, Centro, Noreste, Pampeana, Oeste and Patagónico tournaments.
The tournament took place from 1998–2004, then was re-launched in 2009, in an effort to bring provincial clubs to the same level as the teams from Buenos Aires.
The 32 teams are split into two divisions, the Zona Campeonato and Zona Ascenso, both made up of 16 teams. In the second half of the season, both zones start again with the 8 best ranked teams, concluding with semi-finals and a final.
