Hāpuna Beach State Recreation Area is a large park and sandy beach on the Big Island of Hawaii. The Hapuna Beach Prince Hotel is also located adjacent to the beach. Hāpuna (literally, "spring" or "pool" in Hawaiian) is popular with residents and visitors.

This is one of a few other white sand beaches on the west coast of the Big Island. The few others include Kua Bay (Manini'owali Beach), Kaunaʻoa Bay, known as Mauna Kea Beach, and Samuel M. Spencer Beach Park. It was named the Best Beach in America by Florida International University professor Stephen Leatherman, known as "Dr Beach", in 1993.
