Ben Lomond is a rhyolite lava dome near Lake Taupo in New Zealand's North Island. Located about eight kilometres north-northeast of Kinloch, it rises to a height of 744 metres above sea level.

Ben Lomond erupted about 100,000 years ago, producing two lava lobes that flowed around 3.5 kilometres south and southwest from a vent about one kilometre south of Poihipi Road. Much of the lava formed grey banded obsidian as it cooled. Crystalline rhyolite and pumice were also produced.
