Casa Rosada Presidential Museum, Presidential museum at Plaza de Mayo, Buenos Aires, Argentina.

The Casa Rosada Presidential Museum occupied rooms inside the Casa Rosada, the seat of the Argentine presidency on Plaza de Mayo in Buenos Aires. Created on 27 May 1957, it gathered personal objects, portraits, documents and sculptures of former presidents, shown only once at least thirty years had passed since the end of their mandates. Its collection was moved in 2010 to the present Museo Casa Rosada.

The museum opened in 1957 when sections of the government palace were converted into public exhibition spaces to show Argentina's political journey. This transformation allowed the nation's history to become accessible to visitors.

The collection was built around the presidency as an institution: it held the batons and sashes of office, among them the sash Julio Argentino Roca wore during his second term. It also kept personal belongings of the presidents, such as Hipólito Yrigoyen's bowler hat and cane and a Chinese porcelain fountain that belonged to Bernardino Rivadavia.

The building sits centrally at the main plaza, making it easy to reach on foot and combine with other sights in the area. Visitors should check current opening hours and access requirements in advance to plan their visit properly.

The museum's collection included the presidential sash worn by Julio Argentino Roca during his second term, along with the batons and sashes of several other presidents. It also held carriages such as the Cabriolet Mylord used by José Evaristo Uriburu and a Landau belonging to Roca. In 2010 the entire collection moved to the current Museo Casa Rosada.
