Colegiales is a barrio or district in Buenos Aires, Argentina. It is located between Alvarez Thomas av., Forest av., De los Incas av., Virrey del Pino st., Cabildo av., Jorge Newbery st., Crámer st. and Dorrego av. This neighborhood offers a vast amount of contrast and opportunities.

There are large and tall buildings that go from the Crámer street to Avenida Cabildo and traditional houses up to three stories. This district has become a busy one with many pedestrians and cars on the streets. This neighborhood is mainly residential, with some non-residential areas like the classification yard in the north-east zone, the fairs in the south-west (where until the late 1960s there was another classification yard), and the UCA Colegiales campus in the south-east.

The history of Colegiales is the same as the barrio of Chacarita because it used to be called Chacarita de los Colegiales. This neighborhood had chacras and quintas (smallholdings), where the Jesuits hosted retreats with their students. When this order was expelled in 1767, the lands were expropriated by the Spanish Crown. Beginning with the government of Bernardino Rivadavia in 1826, workers and immigrants from Europe settled in the area that later became the two neighborhoods of Chacarita and Colegiales.

In this district the Club Atlético Colegiales developed, a football club that plays in the regionalized third tier of Argentine football. Today, however, it is in the city of Munro, north of Buenos Aires.

Colegiales is one of Buenos Aires' smallest districts. Its main thoroughfare is Federico Lacroze avenue, where most neighborhood traffic and retail stores are concentrated. Alvarez Thomas avenue is a study in contrasts, lined with single-family rowhouses along one side and almost entirely with apartment blocks along the other. The avenue also separates Colegiales with its neighbor to the south, the barrio of Chacarita.

The Pasaje General Paz (a narrow pedestrian promenade) attracts visitors near and far, with its mature trees, streams and ornate, balconied Andalusian-style patio. Colegiales is also one of the city's "greenest" areas, being also home to Juan José Paso Plaza, Portugal Plaza, San Miguel de Garicoits Plaza, Colegiales Plaza and Mafalda Plaza -known for its whimsical art donated to it by renowned local cartoonist Joaquin Lavado ("Quino").

The Colegiales Athletic and Social Club is probably the neighborhood's favorite social venue. Located on 2860 Teodoro García Street, it was famous in decades past for Roberto "Polaco" Goyeneche's frequent Tango recitals there. Colegiales was also home to the city's first cinema, Las Familias. The cinema was probably better-known, however, for the people who had it built than for its distinction as a historical first. Though now a distant memory, the colorful Anselmis entertained generations of locals with their namesake circus on Lacroze and Cabildo Avenues. Nnone of these establishments still exist, as they either shut down or relocated to the more upscale Belgrano, to the east.

The Argos Cinema (on 3455 Federico Lacroze Ave.) was long the most popular in Colegiales, as it included a cinema, theatre, meeting hall (popular with evangelists) and a dance hall. It was renovated and reopened in May 2012 as the Vorterix Theater, a music venue with a 1500 capacity theater which also houses the radio station Vorterix Rock. Another radio station, Radio Metro (95.1 MHz), is also based in Colegiales, on Conde street.
