Palacio de Gobierno de Jujuy, Government palace in San Salvador de Jujuy, Argentina.

The Palacio de Gobierno de Jujuy is a government building designed in Beaux-Arts style, featuring three stories with symmetrical facades and decorative stone work across its exterior. The structure displays the balanced proportions and refined ornamentation typical of this architectural approach.

In 1901 Provincial Law No. 48 ordered the expropriation of a plot on San Martín street, facing what was then Plaza Urquiza, for a new government house. Engineer Fernando Lavenas drew up the plans and budget in 1902, and works began on 2 June 1908 under builder José Stramandinoli. A legal conflict halted the site in 1912; work resumed in 1918 and the building was inaugurated in 1921.

The first floor features the Flag Room decorated in Renaissance style, where visitors can see the flag donated by General Manuel Belgrano to the province. This space reflects how the building serves as a keeper of provincial identity and memory.

The building sits on Plaza Belgrano at San Martin 450 and operates during standard government business hours. Guided tours can be arranged in advance for visitors interested in seeing the interior spaces.

A major fire in 1950 threatened the historical flag, which was temporarily moved to the bishop's residence while repairs took place. The flag returned to its place in 1952 once restoration work was finished.
