Caerphilly Mountain () lies between Cardiff and Caerphilly at the southern edge of the South Wales Coalfield. Its summit is  above sea-level.

Since 1957 there had been a small wooden snack bar near to the summit. In September 2011 this was replaced by an eco-friendly permanent building, with under floor heating, solar panels and rainwater-flushed toilets, at a cost of £300,000. The mountain includes Caerphilly Common ().

The climb features regularly on the Tour of Britain cycle race, with double climbs in the 2012 and 2013 races.
