Estadio Luis Valenzuela Hermosilla, Municipal football stadium in Copiapó, Chile

Estadio Luis Valenzuela Hermosilla is a football stadium in Copiapó with concrete stands and a capacity of around 8000 spectators. The venue hosts league matches and various community events throughout the year.

The stadium opened in 1960 and quickly became the primary sports center for the Atacama region. It has supported local football development through several decades of regional competition.

The ground hosts Club de Deportes Copiapó, Regional Atacama before it, and now also CEFF Copiapó and Audax Italiano de Paipote. The seats carry colours taken from Colla indigenous craft motifs, a local reference visible from the stands. The stadium shares its grounds with the Orlando Guaita Botta indoor hall, a 50 x 25 m municipal pool and Chiledeportes regional offices.

There are two access points: a pedestrian entrance to the restricted areas and a vehicle entrance on a perimeter ring road. Ticket offices sit at the Conrado Araya vehicle entrance and at the gallery entrance on Avenida Copayapu, with Chiledeportes offices relocated to the south-east wing. The pitch is synthetic and semi-sunken, which improves sightlines from the stands.

The 2009-2011 rebuild was total: Socovesa replaced the old ground with a new FIFA-standard stadium on the same site, inaugurated on 12 November 2011 with minister Laurence Golborne present. The stands' seat colours take motifs from Colla indigenous craft, and a roofed "plaza sombreada" links the west stand to Parque Schneider.
