Sompoton or Sumpotan, is a mouth organ made from a gourd with bamboo pipes in northern Borneo.

[2][3][4] A sompoton consists of eight pieces of bamboo pipe inserted into a dried gourd sealed with bees' wax, which serves as a wind chamber.

Unlike a bamboo flute, which is a straight pipe, the sompoton is a 'mouth organ' as it contains vibrating reeds.

In Kota Kinabalu, capital of Sabah, at the Anjung Kinabalu crafts market one is likely to find 'ornamental sompotons' with only two reeds; but at the Sabah Cultural Centre one finds completely functional/playable sompotons with the full complement of 7 reeds.

Traditionally, the individual pipes have their own names, such as lombohon, monongkol, suruk, baranat, randawi, tuntuduk and tinangga.
