The Juréia-Itatins Ecological Station is an ecological station in the state of São Paulo, Brazil. It fully protects a well-preserved area of Atlantic Forest and associated ecosystems along the coastal plain and mountains of the south of the state, home to endangered species of mammals and birds. There is some threat from illegal gathering of heart of palm.
Average annual temperature ranges from. Average annual rainfall is. The climate is tropical humid with no dry season. At least of rain falls in the driest month. The main biome is Atlantic Forest, with ecosystems typically associated with it including pioneer formations of marine influence, beaches, salt marches, rocky shores and lowland and submontane rainforest. There are fields of open "campo" vegetation at the higher levels, and mangroves along the coast. It has one of the best preserved areas of Atlantic Forest in Brazil. Some of the beaches are sheltered between rock formations, while others have long stretches of fine sand.

History
The Serra dos Itatins State Forest Reserve, preserving a remnant of forest in the Serra dos ltatins, was created by decree 31.650 of 4 August 1958. Part of the Juréia area was chosen by NUCLEBRÁS in the 1980s for the site of two nuclear power plants, Iguape 4 and Iguape 5. NUCLEBRÁS withdrew from the area in 1985 and a campaign was launched to protect the forest. On 20 January 1986 governor André Franco Montoro created the Juréia-Itatins Ecological Station by decree 24.646 with an area of about to ensure the integrity of the existing ecosystems. The ESEC incorporated the state forest reserve, lands declared vacant by the state and other lands along the coast of São Paulo state. The main objectives are preservation of nature and conducting scientific research. An area for the Guarani Indians was excluded, as was an area used for agrarian reform. The boundaries were redefined by law 5.649 of 28 April 1987. Law 12.406 of 13 December 2006 redefined the boundaries of the ESEC and reclassified the areas of the Despraiado Sustainable Development Reserve, Itinguçu State Park, Prelado State Park and Barra do Una Sustainable Development Reserve. It also excluded the areas to the north of the ESEC that were now part of the Banhados de Iguape Ecological Station. The decree created the Juréia-Itatins Mosaic of conservation units with about. It included the Juréia-Itatins Ecological Station, Itinguçu and Prelado state parks, Despraiado and Barra do Una sustainable development reserves and the Ilhas do Abrigo e Guararitama Wildlife Refuge. This law was declared unconstitutional by the Procurer General of Justice of São Paulo on 11 September 2007. The mosaic was suspended in 2009. A motion was passed on 29 June 2012 repudiating the order for 300 families of traditional residents to withdraw from the ESEC. Law 14982 of 8 April 2013 again altered the limits of the ESEC, re-categorising some areas. These were the Itinguçu State Park, Prelado State Park, Barra do Una Sustainable Development Reserve and Despraiado Sustainable Development Reserve. The areas called Banhado Pequeno and Banhado Grande with in the Banhados de Iguape Ecological Station were incorporated in the ESEC, as was the area called Colinas Verdes. An area of to the north of the EXEC was excluded. The same law recreated the Juréia-Itatins Mosaic made up of the Jureia-Itatins ESEC, Itinguçu and Prelado state parks, Despraiado and Barra do Una sustainable development reserves and the Ilhas do Abrigo e Guararitama RVS. The ESEC as of 2016 had an area of. It is part of the Lagamar mosaic.
