Sarawak Chamber is the largest known cave chamber in the world by area and the second-largest by volume after the Miao Room in China. It is in Gua Nasib Bagus (Good Luck Cave), which is located in Gunung Mulu National Park, in the Malaysian state of Sarawak on the island of Borneo.

The chamber was discovered by three British cavers, Andy Eavis, Dave Checkley, and Tony White, in January 1981 during the Mulu'80 Expedition. The story of how it was discovered is told in the books Underground Worlds and Giant Caves of Borneo.

Later named Sarawak Chamber, it measures 600 meters (2,000 ft) long, 435 meters (1,427 ft) wide, and a maximum of 115 meters (377 ft) high, and was estimated as three times the size of the Big Room in Carlsbad Caverns National Park, New Mexico, then thought to be the largest underground chamber. Its volume and area were checked by laser scanning in 2011 and were found to be 9,579,205 cubic meters (338,286,400 cu ft) and 164,459 square meters (1,770,220 sq ft) respectively.

To reach Sarawak Chamber, one must follow a river upstream from the cave entrance. This long passage has a roof up to 60 meters (200 ft) high and may require some swimming and a traverse along a ledge. Accompanied visits can be arranged by the National Park.
