Parque Natural do Fogo (Fogo Natural Park), on the island of Fogo, is one of nine "natural parks" in the country of Cape Verde, which may or may not be the equivalent of national parks in other countries.

Most of the park is in Santa Catarina do Fogo, the northeastern part is in the municipality of Mosteiros.  The western park boundary is overlayed with the Santa Catarina do Fogo-São Filipe municipal boundary.  The area includes the Fogo Volcanic Important Bird Area. The Insular Plate was an ancient oceanic plate that began subducting under the west-coast of North America around the early Cretaceous time.  The Insular Plate had a chain of active volcanic islands that were called the Insular Islands.  These volcanic Islands however collided then fused onto the west-coast of North America when the Insular Plate jammed then shut down ending the subduction zone. American Samoa, located within the geographical region of Oceania, is one of only two possessions of the United States in the Southern Hemisphere, the other being Jarvis Island.

The five volcanic islands are: Tutuila, Aunu'u, Ofu, Olosega, Ta'u.  The coral atolls are: Swains, and Rose Atoll.  Of the seven islands, Rose Atoll is an uninhabited Marine National Monument.
