Tantauco Park (Spanish: Parque Tantauco) is a 1,180 km² (456 sq mi) private natural reserve on the south end of Chiloé Island in Chile. The park was created by Chilean business magnate and President of Chile Sebastián Piñera in 2005 in order to protect 118,000 hectares of the region's unique ecosystem. Piñera owns the foundation Fundación Cultura y Sociedad (formerly Fundación Futuro), which runs the park.
