Anfiteatro Manuel Antonio Ramírez, Open-air amphitheater in Posadas, Argentina

The Anfiteatro Manuel Antonio Ramírez is an open-air amphitheater built into the natural bluff of Cerro Pelón at Punta Gómez, on the Paraná River in Posadas. Its site lies where the Costanera Norte and the former Parque Japonés once stood, at the end of Avenida Costanera Monseñor Jorge Kemerer. The grounds hold roughly 4,000 to 5,000 seated spectators, expandable to 7,000 with mobile stands.

Posadas agreed in 1961 to host the 29th Argentine Basketball Championship, held in February 1962, but lacked suitable infrastructure. Governor César Napoleón Ayrault commissioned the amphitheater from architect Jorge "Cacho" Pomar and engineer Eugenio Beghé; it was built in three months and inaugurated on 17 February 1962. In November 1963 it hosted the first Festival de la Música del Litoral, repeated annually until 1967.

The stage was named "Alcibíades Alarcón" in the 1990s by the Concejo Deliberante, honouring a Misiones singer-songwriter, poet and composer. The venue also hosts the estudiantina's "shows de scola", recitals and public events, all open-air and amplified, audible across the residential neighbourhood.

The venue sits by the river and is accessible by public transportation, with clear signage around the grounds. Since it is an open-air space on a slope, visitors should prepare for changing weather and bring sun protection on bright days.

The stage was named "Alcibíades Alarcón" by the Concejo Deliberante in the 1990s, honouring a Misiones singer-songwriter, poet and composer. The amphitheatre itself honours Manuel Antonio Ramírez, an agronomist, poet and journalist born in Buenos Aires in 1911 who worked in Misiones; the name was suggested by Aníbal Cambas, president of the Junta de Estudios Históricos.
