Mathews Tuya is a tuya in northcentral British Columbia. It is one of the six tuyas close to Tuya Lake. It has been partly glaciated and Ar-Ar geochronology shows that is it about 730,000 years old. It mainly comprises palagonitized tephra (tuff, lapilli tuff, tuff breccia) but also has a few dykes and jointed lava flows on its flanks. The top still has flat-lying lava flows erupted after the tephra pile grew above the surface of the enclosing lake. The other volcanoes in the area include Tuya Butte, South Tuya and Ash Mountain. The volcanoes in the region form part of the Northern Cordilleran Volcanic Province.
