Estadio Municipal Doctor Olegario Henríquez Escalante, Municipal stadium in San Antonio, Chile

Estadio Municipal Doctor Olegario Henríquez Escalante is a sports facility in San Antonio with a grass field and seating areas for spectators. The venue hosts football matches and local athletic competitions throughout the year.

The stadium opened on 5 May 1957 as Estadio Municipal de San Antonio, with covered stands, hot and cold water in the changing rooms, a gym and an Olympic-size grass pitch. Its wooden stands later cut capacity to 2,024. The first stone of a FIFA-standard rebuild was laid on 10 August 2018, a 15,000-million-peso project whose structural work ended in 2021; a 2022 Contraloría report found serious faults, delaying opening beyond three years, with the MOP targeting 2025. It honours Doctor Olegario Henríquez Escalante, a physician and former mayor of San Antonio.

The stadium's name honours Doctor Olegario Henríquez Escalante, a physician who served as mayor of San Antonio. Its home club, San Antonio Unido, plays in the Segunda División Profesional, Chile's third tier, so match days here are local, lower-league football rather than top-flight fixtures.

The stadium stands at Avenida Barros Luco 2595, at the corner of Diputado Carlos Demarchi, and has artificial lighting for night matches. The site includes 223 car parking spaces and 140 bicycle spaces. The opening has been delayed for more than three years after a 2022 Contraloría report found serious flaws in the works, and the MOP targets inauguration in 2025.
