Peninsula, extending northeast from the island of New Britain , Papua New Guinea.
Located in the South Pacific Ocean, the Gazelle Peninsula is about 50 mi (80 km) wide but tapers to 20 mi (32 km) where it joins the mainland. From coastal plains its surface rises to 7,999 ft (2,438 m) at Mount Sinewit in the central Baining Mountains. The peninsula is volcanically active and highly fertile, with cocoa and copra plantations along the coast. The area is the most populous portion of New Britain and was the base of German settlement late in the 19th century.
