The Torneo del Interior A is an annual rugby union competition in Argentina.

Teams qualify from different tournaments along the provinces of Argentina, such as Litoral, Noroeste, Córdoba, Nordeste, Pampeano, Oeste and Patagónico.

The original tournament was held from 1998 to 2004, being re-launched in 2009, in an effort to bring provincial clubs to the same level as the teams from Buenos Aires.

[1] Buenos Aires clubs do not participate in this competition so they take part in the Top 12 organised by the URBA.
