The Gazelle Peninsula is a large peninsula in northeastern East New Britain, Papua New Guinea located on the island of New Britain within the Bismarck Archipelago, situated in the southwestern Pacific Ocean. The Rabaul caldera is located on the northern tip of the peninsula. Upon the Gazelle Peninsula are the Baining Mountains, of which the highest point is Mount Sinewit at 2,063 metres (6,768 ft). The Gazelle Peninsula houses Vulcan Crater and Mount Tavurvur, both of which conducted volcanic activity in the 20th and 21st centuries and have provided extremely fertile soils. The body of the Gazelle Peninsula is about 80 kilometers. The southern isthmus upon which the Gazelle Peninsula is connected to the main body of East New Britain is reduced to about 32 kilometers.

Ethnically the people are typically of Melanesian descent and are referred to as Tolai by title of government. A second and less common indigenous people referred to as Baining, are semi-nomadic and tend to live in the Baining Mountains. They are distinct from the Tolai's Melanesian ethnicity. The Tolai are regarded as being the most successful people of Papua New Guinea; defined by wealth, sophistication, adaptation to modern culture, and instinct for trade.
In Tolai society, currency is used in similar fashion to coin via the medium known as tambu, a shell. Tambu can be bound together as coils to form alternative values and may be used to purchase goods in the Gazelle Peninsula. Marriage for Tolai is typically handled in economic fashion between two groups known as moieties and the son of one family is responsible for paying the bride-price in tambu to the family of the daughter. Marriage of two people within the same moiety is not allowed and the bride-price is generally determined by family status and wealth of the daughter.
