Tham Lot cave is a cave system with a length of 1,666 meters near Sop Pong in Pang Mapha District, Mae Hong Son Province, northern Thailand. The Nam Lang River flows through the cave which is filled with stalactites, stalagmites, columns, and flowstone. The cave is a karst cave set in Permian age limestone. The cave has a large population of bats and Himalayan swiftlets. In Tham Lot and other caves nearby teakwood coffins have been discovered which are thought to have been carved by the Lawa tribes people thousands of years ago.
Another cave in the area, the second longest known cave in Thailand, is Tham Mae Lana, which is 12 kilometres long. This was explored by Australian expeditions between 1984 and 1986.
