Jacarepaguá (Portuguese pronunciation: [ʒakaɾepaˈɡwa]), with a land area of 29.27 square miles (75.8 km2), is a neighborhood situated in the West Zone of Rio de Janeiro, Brazil.

Jacarepaguá is divided into the following sub-areas (sub-bairros), which nowadays are already considered different neighborhoods: The suburb is known for large open areas where events and shows, such as the last Rock in Rio, take place.

The bairro contains the Camorim center of the 12,500 hectares (31,000 acres) Pedra Branca State Park, created in 1974.

Recently, works have been done to build an Olympic Village in an area disputed by Jacarepaguá (or JPA) and Barra da Tijuca, a neighborhood nearby.

Jacarepaguá is a middle-class neighborhood, but one of Rio's largest slums, Cidade de Deus, and others like Favela Covanca, Barão, Inácio do Amaral, etc.
