Maré is a neighborhood and favela in the North Zone of Rio de Janeiro, Brazil. It is a grouping of several favelas, suburbs with houses, and housing complexes. With approximately 130,000 residents, it is one of the largest slum complexes in Rio de Janeiro, a consequence of the low indicators of social development that characterize the region. In 2014 it was featured in a BBC Documentary series Welcome to Rio which highlighted issues with gangs and its pacification.
