Angra dos Reis is a Brazilian municipality located in the south of the state of Rio de Janeiro. It lies on the seaside and has 365 islands along its coastline. It covers an area of 816.3 km², and its population, according to IBGE estimates for 2024, was 179,120 inhabitants. Its neighboring municipalities are Paraty, Rio Claro and Mangaratiba, within the state of Rio de Janeiro, and Bananal and São José do Barreiro on the São Paulo side.
Most of the urban area is surrounded by hills, which has contributed to it being affected several times by natural disasters such as landslides. According to the 2010 Census, about 36% of Angra's population lived in favelas, located on hills or in mangrove areas. This placed the municipality tenth among Brazilian cities in terms of the proportion of households in this type of urban settlement in the country.
