Mesón Group (Spanish: Grupo Mesón) is a Cambrian sedimentary formation located in the Argentine Northwest and nearby parts of Bolivia. The group members rest unconformably on top of the Ediacaran–Cambrian Puncoviscana Formation. According to G.F. Aceñolaza, the Mesón Basin – the sedimentary basin that originated the Méson Group – lay between Arequipa Craton and Río de la Plata Craton.
Mesón Group compromises three formations: Chahualmayoc Formation at the top, Lizoite Formation at the base and Campanario Formation in-between.
