Mashike Mountains (増毛山地, Mashike Sanchi) are a group of mountains on the western coast of Hokkaidō. The mountain range is divided into two regions by the Hamamasu River. The northern region is a group of volcanic mountains called Shokanbetsudake Mountains. The southern region is known as the Kabato Mountains. The Mashike mountains lie between the Teshio Mountains to the north and the Ishikari Plain to the south. Mashikie mountains includes part of Shokanbetsu-Teuri-Yagishiri Quasi-National Park.
