Finisterre Range, mountain range at the base of the Huon Peninsula, northeastern Papua New Guinea, in the southwestern Pacific Ocean. It comprises a section of the northern boundary of the great Central Depression. Tributaries rising in this range feed the Markham and Ramu rivers, which flow in opposite directions through the depression. The Finisterre Range reaches its highest elevation of 13,533 feet (4,125 metres) at an unnamed peak.
