Nuñez is a 'barrio' or neigbourhood of Buenos Aires, Argentina. It is on the northern edge of the city on the banks of the Rio de la Plata. The barrio of Belgrano is to the south east; Saavedra and Coghlan are to the west; and Olivos, in Buenos Aires Province, is to the north.

The barrio has an area of 3.9 km² and a population of over 50,000. It is bounded by the streets Avenida Cabildo , Crisólogo Larralde, Zapiola, Congreso, Udaondo, Cantilo and Avenida General Paz .

It was founded by Don Florencio Emeterio Núñez along with the neighbouring Saavedra barrio. On Sunday 27 April 1873, the railway opened, bringing 2,000 people for a banquet and speeches. Following that event, the land was parcelled and building commenced. Núñez donated the land for the railway station, hence the station and the neighbourhood bear his name.

The area is quite built-up with apartments and much commercial activity, especially along Avenida Cabildo and Avenida del Libertador . Residential streets are generally smart and upmarket, with shady villas, just like much of the rest of the north of the city. There are two squares - Plaza Balcarce and Plaza Félix Lima. Between Avenida del Libertador and the shore, there are large areas of open space, where sports clubs and the 'Estadio Monumental' are located.
