Bunaken National Park is a marine park in the north of Sulawesi island, Indonesia. The park is located near the centre of the Coral Triangle, providing habitat to 390 species of coral as well as many fish, mollusc, reptile and marine mammal species. The Park is representative of Indonesian tropical water ecosystems, consisting of seagrass plain, coral reef, and coastal ecosystems.

It was established as a national park in 1991 and is among the first of Indonesia's growing system of marine parks. It covers a total area of 890.65 km², 97% of which is marine habitat. The remaining 3% of the park is terrestrial, including the five islands of Bunaken, Manado Tua, Mantehage, Nain and Siladen. The southern part of the Park covers part of the Tanjung Kelapa coast.

North Sulawesi is considered to be a 'young' formation, of 5-24 million years of age. The region has undergone explosive volcanism 1.5-5 million years ago, which resulted in the volcanic tuff that characterizes the existing topography. Manado Tua is an inactive volcano formed in a classical cone shape and rising over 600 m above sea level, the highest elevation in the park. Bunaken Island also has volcanic origins with a significant amount of uplifted fossil coral. Nain Island is also a dome-shaped island, 139m in height. Mantehage Island is relatively flat and seems to be sinking into the sea. The island has extensive mangrove forest flats, partially separated by saltwater channels. Siladen is a low-lying coral sand island with no significant topography. Arakan-Wawontulap and Molas-Wori on the mainland of North Sulawesi are relatively flat areas at the base of volcanic hills. The absence of a continental shelf allows the coastal area of the park to drop directly down the continental slope. The sea depth between the islands of the park is 200 to 1,840 metres.

A very rich coral ecosystem covers most of Bunaken National Park, dominated by fringing reef and barrier reef corals. There are about 390 species of coral recorded in the waters of the Park. A distinct feature is a 25-50 metre vertical coral wall which is inhabited by 13 coral genus. The seaweeds that can be found here include Caulerpa, Halimeda, and Padina pavonica species, while the dominant seagrasses, in particular in the islands of Montehage and Nain, are Thalassia hemprichii, Enhallus acoroides, and Thalassodendron ciliatum. The park is also abundant in different species of fish, marine mammals and reptiles, birds, molluscs and mangrove species.
