The Bendeleben (ben-del-ae-bin) Mountains are a mountain range on the heart of the Seward Peninsula in Nome Census Area, Alaska, United States. This range forms a major divide between drainage basins draining into the Pacific Ocean and the Arctic Ocean. The tallest peak, Mount Bendeleben is 3,730 feet (1,140 m) at the summit, and is located on the west end. Bits of the range go into the Bering Land Bridge National Preserve, but most of the peaks remain unclaimed. The Tubutulik River flows in the area.
