Estadio Carlos Augusto Mercado Luna, estadio de fútbol en La Rioja, Argentina

Estadio Carlos Augusto Mercado Luna is a football venue in the city of La Rioja, Argentina. It has four new grandstands positioned on different sides of the field, with two along the sidelines and two behind each goal, providing seating for spectators.

The stadium was inaugurated in 1959 and has served the local football community since then. A major renovation featuring new grandstands was completed in 2019 to improve comfort and capacity.

Locals call the ground Estadio de Vargas, after the neighbourhood, and the name is still used alongside the official one. It hosts the important matches of the two local clubs of the Liga Riojana de Fútbol, Américo Tesorieri and Andino. The reopening on 19 May 2019 was marked by a friendly against Arsenal de Sarandí, who won 2-0 with goals from Lucas Necul and Leonardo Marchi.

The stadium is easily accessible and located near streets where pedestrians can walk to it. The layout allows visitors to enter the grounds and move between the stands without difficulty.

The stadium was formerly known as Estadio de Vargas, named after the neighborhood. This name is still widely used by locals and reflects the long connection between the place and the stadium.
