The Ilha Anchieta State Park (Portuguese: Parque Estadual da Ilha Anchieta) is a state park in the state of São Paulo, Brazil The Ilha Anchieta State Park covers the Ilha Anchieta, an offshore island in the Atlantic Ocean in the municipality of Ubatuba, São Paulo.

It is south of the town of Ubatuba, east of the city of São Paulo.

[9][10] When Europeans arrived in the 16th century the island was occupied by the Tupinambá people.

The island contains more than 2,000 square metres (22,000 sq ft) of preserved historical buildings, as well as ruins of the prison, barracks and civil village of the correctional colony of Porto das Palmas.

This reversed a prior decree that gave administration of the island to the department of urbanization and improvement of resorts.
