Subdivisions

The city is commonly divided into the historic center (Centro); the tourist-friendly wealthier South Zone (Zona Sul); the residential less wealthy North Zone (Zona Norte); peripheries in the West Zone (Zona Oeste), among them Santa Cruz, Campo Grande and the wealthy newer Barra da Tijuca district. Rio de Janeiro is administratively divided into 33 distritos (districts) named Regiões Administrativas ("Administrative Regions") and 165 bairros (neighborhoods).

Subprefectures are officially grouped into four regions (or "zones"), taking into account geographic position and occupation history; however these do not have any administrative or political power over the municipality. The official political division of the municipality takes into account historical-cultural characteristics to divide the neighborhoods. Most of its population is concentrated in the neighborhoods of Campo Grande, Santa Cruz, Bangu, Tijuca, Realengo, Jacarepaguá, Copacabana, Barra da Tijuca, Maré, Guaratiba and Taquara together, these eleven neighborhoods concentrate a population of 1.5 million inhabitants, according to the 2010 census.

Centro or Downtown is the historic core of the city, as well as its financial center. Sites of interest include the Paço Imperial, built during colonial times to serve as a residence for the Portuguese governors of Brazil; many historic churches, such as the Candelária Church (the former cathedral), São Jose, Santa Lucia, Nossa Senhora do Carmo, Santa Rita, São Francisco de Paula, and the monasteries of Santo Antônio and São Bento. The Centro also houses the modern concrete Rio de Janeiro Cathedral. Around the Cinelândia square, there are several landmarks of the Belle Époque of Rio, such as the Municipal Theatre and the National Library building. Among its several museums, the Museu Nacional de Belas Artes (National Museum of Fine Arts) and the Museu Histórico Nacional (National Historical Museum) are the most important.

The South Zone (Zona Sul) is composed of several districts, among which are São Conrado, Leblon, Ipanema, Arpoador, Copacabana, and Leme, which compose Rio's Atlantic beach coastline. The neighborhood of Copacabana beach hosts one of the world's most spectacular New Year's Eve parties ("Reveillon"), as more than two million revelers crowd onto the sands to watch the fireworks display. From 2001, the fireworks have been launched from boats, to improve the safety of the event.

The North Zone (Zona Norte) begins at Grande Tijuca (the middle class residential and commercial bairro of Tijuca), just west of the city center, and sprawls for miles inland until Baixada Fluminense and the city's Northwest. This region is home to the Maracanã (located in Grande Tijuca), once the world's highest capacity football venue, able to hold nearly 199,854 people, as it did for the World Cup final of 1950. This region is also home to most of the samba schools of Rio de Janeiro such as Mangueira, Salgueiro, Império Serrano, Unidos da Tijuca, Imperatriz Leopoldinense, among others. Some of the main neighborhoods of Rio's North Zone are Alto da Boa Vista which shares the Tijuca Rainforest with the South and Southwest Zones; Tijuca, Vila Isabel, Méier, São Cristovão, Madureira, Penha, Manguinhos, Fundão, Olaria among others. Many of Rio de Janeiro's slums (favelas), are located in the North Zone.

West Zone (Zona Oeste) of Rio de Janeiro is a vaguely defined area that covers some 50% of the city's entire area, including Barra da Tijuca and Recreio dos Bandeirantes neighborhoods. The West Side of Rio has many historic sites because of the old "Royal Road of Santa Cruz" that crossed the territory in the regions of Realengo, Bangu, and Campo Grande, finishing at the Royal Palace of Santa Cruz in the Santa Cruz region. The highest peak of the city of Rio de Janeiro is the Pedra Branca Peak (Pico da Pedra Branca) inside the Pedra Branca State Park. It has an altitude of 1024m. The Pedra Branca State Park (Parque Estadual da Pedra Branca) is the biggest urban state park in the world comprising 17 neighborhoods in the west side, being a "giant lung" in the city with trails, waterfalls and historic constructions like an old aqueduct in the Colônia Juliano Moreira in the neighborhood of Taquara and a dam in Camorim. Santa Cruz and Campo Grande Region have exhibited economic growth, mainly in the Campo Grande neighborhood. Industrial enterprises are being built in lower and lower middle class residential Santa Cruz, one of the largest and most populous of Rio de Janeiro's neighborhoods, most notably Ternium Brasil, a new steel mill with its own private docks on Sepetiba Bay, which is planned to be South America's largest steel works. A tunnel called Túnel da Grota Funda, opened in 2012, creating a public transit facility between Barra da Tijuca and Santa Cruz, lessening travel time to the region from other areas of Rio de Janeiro.
