Estadio Hermanos Antuña, Football stadium in Mieres, Spain.

Estadio Hermanos Antuña is a municipally owned football and athletics ground in Mieres, Asturias, home of Caudal Deportivo. Its two stands hold 2,940 spectators, and the pitch is artificial turf inside a four-lane athletics track. The old main tribune is protected for its cultural interest; the ground was reformed in 2007.

Inaugurated on 16 September 1951 as Nuevo Estadio del Batán, it was renamed Estadio Hermanos Antuña in 1964 to honour Joaquín and Ramón Antuña, brothers who promoted the club in its early years, when it was called Racing de Mieres. Ramón Antuña served as club president for 29 years. The stadium was reformed in 2007.

The stadium is central to the sporting life of Mieres, with local fans gathering regularly to watch football matches. The main grandstand holds protected status as an architectural landmark that reflects the town's sporting traditions.

The ground is municipal property and its pitch is artificial turf, ringed by an athletics track of only four lanes, too few for official competition, which needs six. The two stands hold 2,940 seats; the old main tribune is protected for its cultural interest. The stadium was reformed in 2007.

The facility serves as a dual-purpose venue where football and athletics coexist on the same grounds, a feature uncommon in many local sports complexes. This setup allows athletes and teams to train and compete across multiple disciplines without relocating.
