The Sarawak Chamber is a huge chamber 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. It is considered to be the largest known underground chamber in the world.

The chamber was discovered by three Englishmen in January 1981. Andy Eavis, Dave Checkley and Tony White (all experienced cave explorers) had been exploring the dense, unpopulated area of the Gunung Mulu National Park jungle in Sarawak, in the north of Borneo, in an expedition led by fellow Englishman Ben Lyon. While they were surveying some of the newly found caves in the region, they stumbled into what seemed to be a huge cavern. Even with their powerful lamps, the explorers could not see the other end of the chamber; they had entered the largest known enclosed space in the world.

Later named the Sarawak Chamber, it was three times the size of the Big Room in Carlsbad Caverns National Park, New Mexico, previously thought to be the largest underground chamber. The Sarawak Chamber measured 700 m (2,300 feet) long, 400 m (1,300 feet) wide and at least 70 m (230 feet) high. The chamber is now firmly situated as the largest in the world.
