Bouchard Plaza, Office skyscraper in San Nicolás district, Buenos Aires, Argentina.

Bouchard Plaza is a 26-story, 100-meter office tower in San Nicolás, Buenos Aires, built as a postmodern addition around the former La Nación building. Its lower floors are clad in brick, the upper ones in a glazed curtain wall, and the elevator core sits at the centre, leaving large floor plates with views toward the Río de la Plata and Plaza Roma. It holds about 65,000 m2 of office space.

The newspaper La Nación held a 1955 competition won by SEPRA (Sánchez Elía, Peralta Ramos y Agostini) for new editorial offices and a printing plant on Bouchard Street. The first stage opened in January 1969 with three basements, a ground floor and one upper floor; later stages reached completion in 1975 and 1979–1980. In 2000 La Nación joined Techint and Banco Río in a US$40 million project by HOK and Aisenson Arquitectos, and the tower opened in 2004.

The building's name comes from Bouchard Street, where it stands at number 557, in the San Nicolás ward. Its earlier identity survives in the nickname Edificio La Nación, after the newspaper founded by President Bartolomé Mitre that had its newsroom here until 2013. The lower brick-clad floors once housed the presses, while the upper glazed floors held editorial offices.

Bouchard Plaza is a private office tower, not open to visitors; its lobby and upper floors serve tenants such as Techint and PricewaterhouseCoopers. The building faces Bouchard Street, with Roma Square flanking it to the south and the Eduardo Madero Avenue side handling truck loading. The former newspaper printing plant moved to Barracas, so no pressroom visits are possible here.

The 2004 tower was built on steel columns around the existing La Nación building, so the newspaper kept working inside while the new structure rose. The old facade was then replaced to match the addition. The property passed to the developer IRSA in 2007.
