Hawaiʻi Volcanoes National Park, established in 1916, is a United States National Park located in the U.S. State of Hawaiʻi on the island of Hawaiʻi. It encompasses two active volcanoes: Kīlauea, one of the world's most active volcanoes, and Mauna Loa, the world's most massive volcano. The park gives scientists insight into the birth of the Hawaiian Islands and ongoing studies into the processes of vulcanism. For visitors, the park offers dramatic volcanic landscapes as well as glimpses of rare flora and fauna.

In recognition of its outstanding natural values, Hawaiʻi Volcanoes National Park was designated as an International Biosphere Reserve in 1980 and a World Heritage Site in 1987. In 2000 the name was changed by the Hawaiian National Park Language Correction Act of 2000 observing the Hawaiian spelling.
