Ambitle is a volcanic island on the South Bismarck plate which, together with Babase, another volcanic island, makes up the Feni Islands in the Bismarck Archipelago. The island is located within the Papua New Guinea's New Ireland Province, to the east of the island of New Ireland. It is part of the Tanir Rural LLG local government area.
Ambitle is a stratovolcano, reaching above sea level, located at the southeastern end of the NW-trending 250 km long Tabar-Lihir-Tanga-Feni (TLTF) volcanic island chain. It last erupted in about 350 BCE based on radiocarbon dating. The rock types sampled from Ambitle include feldspathoid-bearing basalt, trachybasalt, phonotephrite, trachyandesite, and trachydacite or quartz-trachyte. Its caldera, wide, contains thermal areas on its western side. Venting of hydrothermal water also occurs in coral reefs to the west of this island. The vents located at Tutum Bay are unique in that the vent fluids and surrounding sediments contain some of the highest concentrations of arsenic in a natural system.
