Barrio Norte (English: Northern neighborhood) is the informal name given to a part of Buenos Aires centering on Santa Fe Avenue and the district of Recoleta.

To the east, the area forms a certain architectural unit that resembles it to Paris, a feature that is progressively lost towards the west, bordering Palermo, where modern apartment buildings predominate.

An unofficial neighborhood, Barrio Norte is roughly equivalent to the Recoleta district, though it generally refers to the portion south of Las Heras Avenue.

Santa Fe Avenue became the preferred venue for upscale shopping in Buenos Aires during the 1950s and '60s, and the profile of the area surrounding it grew in popularity among the emerging Argentine upper middle class, particularly after the 1961 demolition of the National Pentitentiary for the creation of the 8-hectare (20 acre) Las Heras Park.

With the advent of popular indoor shopping malls in the 1980s, Santa Fe lost some of its allure, especially with theater-goers, even though it remains a very active commercial thoroughfare.
