The Campeonato Argentino de Mayores is an annual rugby union competition in Argentina. Although it is usually treated as such it is not strictly a provincial competition as the 25 competing teams do not represent the 25 provinces of Argentina but rather the unions that make up the Unión Argentina de Rugby (UAR). Some of these unions represent more than one province for example Noreste represents the provinces of Chaco and Corrientes.
