Pavilion Mountain is a mountain in the Marble Range in the South Cariboo region of the South-Central Interior of British Columbia, Canada, located northeast of the ranching and First Nations community of Pavilion and to the north of Marble Canyon and immediately south of Kelly Lake, which is the focus of Downing Provincial Park. The term Pavilion Mountain is also used to refer to the historic ranch and associated rangeland on the "bench" on the mountain's southwestern side, and also to the road which traverses that benchland and the mountain's western shoulder and is the route of the Old Cariboo Road. The switchback descent from the summit of the road was known as the Rattlesnake Grade and was an infamous stretch of the old wagon road. From a junction at the road-summit, a road leads east along the spine of the mountain to the peak, which is the site of a microwave relay and former fire lookout. The mountain's only named subpeak, Mount Carson, at 2005 metres (6578 ft, prominence: 120 m), is southeast of the fire lookout and is named for the original owner of the ranch and was briefly misapplied as the name of Pavilion Mountain. Robert Carson was one of the first settlers in the region and whose sons later became prominent MLAs and provincial cabinet ministers.
