Costa dos Corais Environmental Protection Area, Marine conservation area in Pernambuco and Alagoas, Brazil.

The Costa dos Corais Environmental Protection Area stretches 135 km from Tamandaré, Pernambuco, to Maceió, Alagoas, covering over 413,000 hectares. It is Brazil's largest marine conservation unit, managed by ICMBio. The photograph shows a tan and grey rock reef running diagonally across green-blue water, with a band of pale turquoise shallows between the reef and a palm-lined sandy beach.

Created by presidential decree on 23 October 1997, the area was established to protect coral reefs, associated ecosystems and threatened species such as the manatee. It is managed by ICMBio, a federal agency linked to the Ministry of the Environment. In 2019 the coast was affected by an oil spill in northeastern Brazil.

The area's name comes from its coral reefs, which form the second-largest reef system in the world after Australia's Great Barrier Reef. The federally managed zone covers four municipalities in Pernambuco and nine in Alagoas, and fishing is prohibited within it. Nationally known beaches such as Praia dos Carneiros and Maragogi lie along its coast.

The protected area stretches 135 km from Tamandaré, in southern Pernambuco, to Maceió, Alagoas, covering over 413,000 hectares across four Pernambuco and nine Alagoan municipalities. Its best-known beaches are Praia dos Carneiros and Maragogi. Fishing is prohibited throughout the area, which is managed by ICMBio, the federal biodiversity agency.

The reef complex here is the second largest in the world, exceeded only by Australia's Great Barrier Reef, according to Brazilian conservation sources. The area also shelters the manatee, a threatened species the reserve was partly created to protect. In 2019 the coast was reached by the oil spill that affected northeastern Brazil.
